b/c your brak light is blown..and all the rest will work but that one.that or you have a fusa that is not working one of the 2
because there is two filiments in the bulb one for brake and signal light and one for running light
Two filaments in the light bulb. One is the tail light, the other is the brake light.
tail light bulbs has two filaments inside. One for regular lights and a second for brake lights. One filament is burnt out. Change the bulb.
Check the switch. It has a different one than the regular brake lights. the light bulb could possibly be blown
AnswerTry checking your fuse for your tail lights in your fuse box if that doesnt work try check for a short in your wiringAnswerI noticed on my 1990 did the same. Also found out it only happens when the TILT wheel is completely down. Try lifting the tilt wheel up and down with someone watching your brake lights. Have not pinned down the source in the column yet, but will keep looking!!!The brake light switch is probably the problem. My '91 had the opposite - the brake lights worked but the 3rd light did not. The brake light switch has 2 terminals - one for brake lights and one for the 3rd brake light. Replace the switch.
On mine, when the lights are off, the left brake light is faint but still works. When the lights are one, the running light is on (faint) but goes out when I hit the brakes. And the turn signal doesnt ever work. When Ive checked the light bulbs they burn out fast. I have been told that replacing the plastic bulb housing will fix this. But I have not tried it yet.
It is possible that one of the bulbs is shorting out. Try replacing the brake light bulbs, if that doesn't work, troubleshoot the brake light switch.
make sure u got a twin lement bulb one element is for tail light other is for brake light sounds like u just put wrong bulb in
The tail light/brake light bulb has two filaments. If one of the filaments is broken, you will get either only tail lights, or brake lights. If a new bulb doesn't work, then you have a broken wire or bad connection in your plug-in.
check your rear light bulbs. it is a two filament light and one is burned out.
They are two stage bulbs two bulbs in one one of the filaments must be out being the one for your brake lights enjoy If the bulbs check okay, check the brake light fuse, if the fuse checks okay, the brake light switch may be out of adjustment or faulty.
