Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

The light bulb on my opener is off when it should be on. If I screw the bulb in or out slightly, it turns on and flickers a bit. When the timer times out, the light goes out. If something crosses the sensor or the door is opened or closed again, the light doesn't come one unless I screw it it in or out again. It has been like this for years! Thanks in advance for any help. -- In the dark

Unplug the opener and remove the bulb. Use a small screwdriver to pull out on the center contact in the light socket. Replace the bulb and plug in the opener.

BMW 650 Tail Light Problem


If you find that your BMW 650 CS/GS/Dakar tail light doesn’t work at all or flickers when riding, chances are the metal power terminals inside the bulb socket are no longer making a good connection with the metal bumps on the tail light bulb. This is a very common problem with the BMW 650 of all makes, models, and years. Fortunately, there is a very easy fix.
Due to excessive vibration, temperature changes, and replacing light bulbs, the two metal power terminal tabs inside the tail light socket deform and get pushed too far back inside the tail light chassis. This prevents the tail light bulb from making good contact with the power terminals and the smallest vibrations can cause the electric connection to break temporarily or indefinitely.

To fix the problem, all you need to do is pry the two metal power tabs forward just a little so that they make a better connection with the metal bumps on the tail light bulb. If you look at the back of the bike, the red tail light casing on the 650 CS/GS/Dakar is held in place with two screws. If you remove these screws the red tail light casing comes off and you have access to the light bulb inside. At this point, turn the ignition on, but you don’t need to start the bike. Remove the light bulb by pushing in and twisting clockwise about 1/8 turn. If the bulb flickered while removing it, then the bent power terminals are most likely the cause.
Looking at the tail light bulb you should see two metal bumps. These bumps need to make a good connection with the two metal power terminals inside the tail light casing. Turn the ignition off and find a small tool that you can use to pry the power terminals forward just a bit. Make sure the bike is off and you don’t want the power terminals tabs inside the tail light casing to touch.
After you have made the adjustment, turn the ignition back to “on” and re-insert the taillight bulb. If the bulb is lit, then you are done. If it still flickers a bit and doesn’t stay lit, then you will need to continue prying the tabs forward until a good connection is made.

Brake Lights Dull or Flickering - All Cars



Dull or Dim Brake Light Repair: If your car has a dull or dim brake light it is dangerous to you and other drivers. A dim brake light is a mystery to most people because the bulb is working, just not correctly. First confirm a new and correct brake light bulb has been installed. Next, turn the ignition key to the "on" position and have a helper depress the brake pedal. With the bulb installed touch a grounded test light to the outer bulb holder ring. If the bulb brightness changes the bulb socket ground has high resistance and needs to be repaired or replaced.

Flickering Brake Light Bulb Repair: A flickering brake light bulb can be very distracting and annoying. A brake light flickers because the power or ground is being obstructed momentarily. The most common cause for this condition is a loose fitting bulb socket. To check for this condition remove the brake light bulb in question, while a helper hold their foot on the brake pedal move the bulb around slightly in the socket. If the bulb flickers replace or repair the bulb socket as needed to regain proper brake light bulb operation. If the brake light bulb socket tests ok wiggle the brake light fuse and wiring at the brake light bulb socket, brake light switch and turn signal switch (American cars). If the brake light bulb flickers repair the component or wiring as needed.
Preferred Procedure: Always replace brake light bulbs with manufacturers recommend replacement bulbs. If you cannot find the correct replacement bulb part number consult an auto parts store for additional manufacturer information.
Common Problems
When brake light bulbs are replaced with the incorrect bulb causing no or dim brake light operation
If the brake lights stay on continuously it could mean the brake light switch has failed or an adjustment is needed.

Need a good vacation timer. Any suggestions?


Copy following link to see analog vacation timers that turn lights on at random times.
Set current time slightly different so lights inside house can turn on-off at slightly different schedules.
Rotate dial to set current time, plug timer into outlet, make sure bulb is good, turn light ON, and plug light into timer.

Multi-function digital timers, such as Woods 59377, and lifetime-warranty Intermatic DT620 also have vacation feature, and timers have 2 outlets, but programming is more complicated than using analog timer.

How to change front turn signal light bulb 1992 cadillac deville


You need a T-15 star bit driver that is referred to as TORX. On the top and bottom of tail light are the screws. Carefully remove the chrome trim then the light pulls out after applying slight upward pressure. Once you twist out the socket the bulb simply unplugs. It should be either a 3057 or 3157 bulb.
