The reason why car led light doesn’t work.
Q:The reason whycar led light doesn’t work.
Many drivers may meet the problem that why the car led light can not work. This is very dangerous for drivers.And for most drivers can not know the real reason.Do not worry ,we will help you solve this urgent and important problem.Generally speaking there are four reasons according to different phenomenours as below.Hope this will be useful for you.
This condition can be nether bulb or Contacts. The Soft Copper Contact metal seems to be a very common problem, even more so than burnt-out bulbs, but first look at the bulb. If it is the Contacts, removing the lens cover and wiggling the bulb, pushing in slightly, should produce a working brake light in certain bulb positions.
The symptoms indicate the Front Brake Switch is out of order. There is a little microswitch acted upon by your front brake hand lever, just at the pivot of the lever. It is attached with some tiny nuts and screws. Loosen the screws ever so slightly and adjust the switch. If that doesn't make your brake light come on when you squeeze the lever, it could be the switch is either stuck or bad. You could give it a squirt of WD40 to free it up. If you remove the switch be very VERY careful not to lose the little piece called the "druckstuck" (literally push piece, very precise these Germans) that goes between the tit on the switch and the lever itself.
You will need to check inside this Rubber Cap as it houses the electrical Switch Contacts for the Rear Brake Pedal. Often it can get dirty in the Cap, so pull the cap off and give the wires a good clean, remove the wires and clean the contacts, reinsert the wires. Clean inside the Cap before reinsertion.
A .Check the Blade Switch at the Rear Brake Pedal. There is a small blade spring which is used to push the tit in the switch back into the switch. The blade spring is supposed to sit on top of a bar that is on the right hand side of the brake pedal and as you depress the pedal it pushes the spring up and then activates the light through the switch. If the blade spring gets under the pedal (which it can easily do) the brake light stays on. Easy to check before starting to pull micro switches apart. Ratso.
B. check this condition first you have to know what is ON, i.e. is that the Brake Light or just the taillight. To do this, Find the microswitch at the Front Brake Lever and note how its tiny "nipple"gets pressed in when the brake lever is disengaged, and is released so that it protrudes when the brake lever is engaged or pulled.
a) When you press the microswitch nipple (using e.g. a fine jeweller’s screwdriver), if it has NOT previously been pressing in properly, your brake light should dim down to the normal taillight mode.
b) The solution is to loosen the two tiny screws ever so slightly and adjust the switch. If that doesn't make your brake light come on when you squeeze the lever, it could be the switch is either stuck or bad. You could give it a squirt of WD40 to free it up. If you do undo the screws completely to clean it or replace it, be very VERY careful not to lose the little piece called the "Druck stuck" (literally push piece, very precise these Germans) that goes between the tit on the switch and the lever itself.
1) If you've just installed new lights (especially flashers) check the car led Bulb Wattage is correct! Don't forget to check the bulbs. And just took the fuse with it. The filament was broken but showed continuity with a VOM check. Sometimes it came on by itself, other times it would light up if I tapped it, and it always came on and stayed on if it was hot from operating and then was turned off and then back on again. teddco.
