Your friend could be right but before spending more money check the cooling fan is free to spin the bulb will not start if the fan isnt spinning.

Have a brand new jonway 50cc 15 miles blew bulb whats wrong

Occasionally bulbs will fail for no reason. Replace the bulb and try again. If it fails again, then you likely have a problem.

How to fit dimmer switch

The dimmer switch you select will depend on the type of bulbs you will be using. The 'original type ' of dimmer works with regular incandescent bulbs and halogen bulbs only. They cost around $15.00. Then there are dimmers for compact florescent (cfl) bulbs and LED lights that are dimmable, as well for regular light bulbs. These types of dimmers are more expensive, ranging in price form around $40.00 upwards.
Light Switches Dimmers

If you are replacing a single pole switch ( just one switch that operates lights) you'll need a single pole dimmer. If you are replacing a 3-way switch ( two switches that operate the same light) you'll need a 3-way dimmer.
Installing the dimmer is pretty straight forward. All dimmers come with installation instructions. Make sure you turn off the circuit breaker for the particular switch you are replacing.

Headlight keeps blowing out 1996 yamaha virago 1100

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Break lights not working properly

silly thing to sugest but would you have the brake/side light bulbs in the wrong way? if you look closley at the bulbs there is two pins either side on the round silver part. 1 pin sits higher than the other, make sure you fit the bulbs in the bulb holders to match the pins on the bulb sounds complicated but it realy is an easy mistake to make.

2004 Landrover Freelander stop/reverse light fuse keeps blowing

I had a persistent problem of hill light warning and TCS warning lights coming on for no apparent reason. There is a wire connection between the stop light switch and the control unit to let the system know when brakes are being applied. Changing the stop light switch cured it. The replaced switch was certainly sticking and the new one was of a different design. Replaced it myself as switch comes with a wiring loom. Need to get on your back under the steering wheel! Not very expensive. My car 2001 TD4

Light flickers when dimmer switch isn't ''just right''

Compact fluorescent bulbs do not work on dimmers.  You have to use standard incandescent bulbs or not dim the lights.

Fan or heater switches bulb gone

Apparently, this problem you are experiencing is quite common in VW MK4 Golfs, it's not the bulb but the lighting connection behind your switch. If you bang the right hand side sides your gan controls your fan lights should appear again. Sounds crazy but it's true. I know few people with VW Golf who have this problem.
