These bulbs are easily changed. They can be ordered for free from the Sunfire service center or can be ordered from Rita's Vintage Audio repair.. See below for contact info.

http://www.sunfire.com/service.asp

You have to pull the cover off of the amp (be careful, there is a limited amount of distance you can have between the main chassis and the top cover because of the bulb wiring once you remove the ocver) which means removing 8 or so screws (4 in the bottom, 4 on the rear) and the cover pulls straight up. The bulb is then contained in the assembly that you can see from the front of the unit that is fastened to the top cover.

The new bulb can be soldered in or spliced in.

How do i bim and brighten dash light 2002 buick lesabre


bim or DIM ? the dimmer switch ! Interior Lamps
The interior lamps consists of two groups, lamps that can not be dimmed and lamps that can be dimmed. This first group consists of lamps that may not be dimmed. This includes those lamps that may be manually turned on by placing the interior lamp switch to the DOME position, or by opening a door or a compartment:
• Door courtesy lamps
• Footwell courtesy lamps
• Instrument panel (I/P) compartment lamp
• Overhead console courtesy lamps
• Reading courtesy lamps
• Rear compartment courtesy lamp
• Roof rail courtesy lamps
• Sunshade vanity mirror lamps

Interior Lamps Dimming
This group of interior lighting includes lamps which may be dimmed. This group uses a combination of class 2 controlled illumination and incandescent lamps:
• Air temperature switch
• Cigar lighter lamp
• Door switches
• Driver information center (DIC) switch
• Headlamp switch
• Head-up display (HUD) switch
• Heated seat switches
• HVAC control assembly
• Instrument panel cluster (IPC)
• Memory function switch
• Radio
• Steering wheel controls
• Window switches
For the interior lighting to be dimmed the following conditions must be met:
• A low light level has been detected by the dash integration module (DIM)
• Headlamp switch is placed in to the PARK or HEAD position
• Ignition switch is placed in the ON position
Then all class 2 displays and all incandescent back lighting will be illuminated to the level set by the instrument panel (I/P) dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all class 2 displays and all incandescent back lighting respond from minimum intensity to maximum brightness.
The DIM supplies battery positive voltage to the coil side of the PRK LP relay in the rear fuse block.
When the I/P dimmer switch is moved from MIN to MAX, then the instrument panel module (IPM), W/CJ2, or climate control panel (CCP), W/C67, applies a message to the class 2 communication circuit to the DIM. The DIM then applies a ground to the park lamp relay control circuit. This energizes the PRK LAMP relay and allows battery positive voltage to be applied through the DIMR fuse to the DIM. The DIM then illuminates the following incandescent lamps through the incandescent dimming output circuit:
• Cigar lighter lamp
• DIC Switch
• Headlamp switch
• HUD switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The DIM also applies a message to the following class 2 controlled illumination components:
• Drivers door module (DDM)
• HVAC control assembly
• IPC
• Radio
The DDM will then send a message through the simple bus interface (SBI) to the RH front door module (RFDM). The door modules will then illuminate the following components through the incandescent dimming output circuit:
• Air temperature switch
• Heated seat switches (W/KA1)
• Memory function switch (W/A45)
• Power door lock switches
• Power window switches
The ground for these components are provided from the DDM and RFDM.
The following components are grounded at G200:
• Headlamp switch
• HVAC control assembly
• IPC
• Radio
• Steering wheel controls
The following components are grounded at G201:
• Cigar lighter lamp
• DIC Switch
• HUD switch

I have a 2002 Buick Rendezvous and the radio and heater control backlights have shut off simultaneously and now only the vent control and trunk release lights work.


I would take a look see at the ground circuits for the none working lights . The incandescent back lighting lamps are then grounded at G200, G301 and G302. You would need factory service info for the location of the grounds .Like this from buick
G200
Right side of the I/P, secured on the underside of the cross car beam, behind the I/P compartment . The I/P compartment is the glove box ,don't know why they just don't say that . You could also check out the power and ground from the componet that's not working ! You can find factory like service info. from alldata

Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and of incandescent lamps.
• The door switches and the window switches
• The HVAC control head assembly
• The radio
• The instrument panel cluster (IPC)
• The steering wheel controls
• The heated seat switch
• The HUD switch
• The lift glass window release switch and traction control switch
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) displays (radio and HVAC control assembly), incandescent lamps, turn on at maximum brightness. When the park lamps are on and the ambient light sensor indicates low light conditions, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The BCM L fuse in the console fuse block, supplies battery positive voltage to the BCM. The I/P courtesy lamps supply voltage circuit of the BCM, supplies battery positive voltage to all the dimmable lamps. When the headlamp switch is placed in the PARK position, the BCM will then dim the interior lamps to the dimming level indicated by the IP dimmer switch. When the driver selects a dimming setting by moving, the IP dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. The incandescent back lighting lamps are then grounded at G200, G301 and G302. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.
The driver may select parade mode by manually turning on the park lamps during daylight conditions. The front park lamp circuit supplies voltage to the instrument panel cluster, radio and HVAC assembly for a park lamp on input, and the displays will become full bright.

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

I usually replace all of my radio lamps with Ultrabright LEDs. They come in many different colours and usually fit the same mounting hole as the incandescent lamps. They will need a current limiting resistor in one of their leads, 2200 ohms to 4700 ohms at 1/4 watt works well. Leds are polarized so make sure that you get the polarity correct. Leds are also about 1/10 the cost of a similar incandescent bulb.

I have a lutron skylark s-600-wh. I would like to know if this dimmer is electronic or magnetic??? I will use it for a series of under the counter kitchen puck lights, and was told that the dimmer...


It is neither - it is rated for incandescent lamps only. It sounds like someone suggested that your puck ligths are being controlled by electronic low-voltage transformers, in which case, if you wanted to stick to the Skylark family, should be an SELV-300P-WH.

If you're not sure about any of this, I suggest calling Lutron's tech support line. It's at 1-800-523-9466, they're available 24/7, and can double-check the recommendation.

A 40 W fluorescent lamp gives out more light than a 4o W filament bulb.explain whether the fluorescent lamp is actually using electrical energy at the same rate as the filament bulb??


The lamps are both using 40 watts of energy, but the fluorescent lamp gives more lumens (visible light measurement) than the incandescent.
Fluorescent gives at least 5000 lumens for 100 watts.
Incandescent gives 1750 lumens for 100 watts.
You can see that if you had a 100 watt incandescent, it would be 1750 and you would only need 35 watts of flourescent.

We have an existing wall mounted occupancy sensor ON/ AUTO/OFF (2 wire with equipment grounding conductor.) Until now, the sensor has controlled two (2) incandescent medium base porcelain lamp holders (60W...


This is not a surprise. Many wall-mounted devices such as occupancy sensors and dimmers operate by leaking a little bit of power through the light fixtures. In the world of incandescent, this was rarely a problem - that little bit of current wasn't enough to excite the bulb. But now that we're living in a world of low-wattage lamp types, that little bit of current is now enough power to excite the lamp and cause what you're seeing. The added detriment is that little bit of pulsing that you see in the CFL can actually wear it out pretty quickly.

The short-term solution is to use the older-style, incandescent lamps.
Another short-term solution would be to attempt using another manufacturer's CFL or try an LED lamp - that's by no stretch a guarantee, you'd be rolling the dice with each lamp choice you made. The higher wattage the lamps, the less likely you'll see an issue.

There are two long-term solutions:
1) Add another lamp - the more lamps the control sees, the less leakage current that goes through each lamp. Several people have solved this by adding a 'dummy' incandescent load (like a 15W or 25W lamp) somewhere in the lighting circuit to take the brunt of the leakage.
2) Change the wall-sensor. Lutron makes one (MS-OPS6M-DV-WH) that has extremely low leakage current and may solve the problem. But the best way to guarantee it won't be an issue is to use a wall-sensor that connects to the neutral wire in the wallbox. Those devices take that leakage current and dump it out the neural wire rather than run in through the light fixture. Lutron makes one of those as well (MS-OPS5AM-WH)

Dont know what the difference is between lamps


these are Panasonic arc lamps .. the numbers 100-120 indicates the intended voltage range of operation .. the /1.3 or /1.4 is the current in amps .. so the 1.4 is slightly higher current and likely a bit brighter .. thats 156 watts vs. 168 watts .. arc lamps are much more efficient than incandescent so 150 watts in an arc lamp is a lot more light than a 150 watt incandescent...
