Great chance it is a bad bulb. There are 2 filaments and one is probably bad.

The ground for the brake lamp. When the tail lights are off, the tail light circuit can act as a ground for the brake light. When the tail lights are on, it can't.

Replace the light bulb. Tail lights are usually dual filament, 2 filaments in one bulb.

Those are completely separate circuits. First check the brake light bulbs to be sure they are not burned out. If they check okay, check the brake light fuse. If the fuse checks okay, check the brake light switch.

The bulb is burnt out. If the problem was a fuse, then all brake lights and probably the dashboard lights would be out as well.

My rear window brake light works, but not my tail light brakes on my 1997 Monte Carlo. What is the problem?

Replace the bulb it works when you turn on the driving lights and when you brake. there are two little springs inside the light one is for the brake light and the other is for the driving light. All you need to do is replace the bulb. good luck.

check the bulb, it has two filaments, one for tail light, another for brake light and indicator. if the turn signal works, it's not the bulb, but a power supply problem.

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.

It depends on if the tail light works or not. What would happen is, the Driving Tester would check your vehicle, registration, insurance, state inspection, and etc. I'm pretty sure that if you have a broken tail light, i.e. the tail light won't light up when you brake, you wouldn't be able to even take the test. If the tail light is cracked, but still works, I don't think it be a problem.

Two filaments in the light bulb. One is the tail light, the other is the brake light.

??? Your brakelights are only supposed to come on when using the brakes. Do you mean that your TAIL LIGHTS don't work? Hey Jose==Your TAIL lights may have a fuse blown or something could be wrong with the head light switch. You just have to check it out. GoodluckJoe The tail light bulb has two filaments in it. One for the tail light and one for the brake light. The brake light part is still connected but the one for the tail light is broken. All of this is inside the bulb. Happens all the time. Just need to replace the tail light bulb.

bulb is out The bulb has two elements in it, one for the tail light and one for the brake. The brake one is also for the directional signals.

The Integra uses a dual-filament bulb in the tail light, which has one contact for the running light (the lights you turn on at night) and another brighter one for the brake light (only goes on when you press the brake pedal). You have replaced the bulb with the wrong type. You will need a 2057 bulb for the Integra.

Check the tail light bulbs. These bulbs do double duty. Thet are both the tail light & the brake light. Tail light part might be burnt out.

User Avatar

If it is a single bulb, it is probably the bulb. Many tail light bulbs have two separate filaments, with the turn/brake being much brighter than the marker light. The tail light and turn/brake circuits are completely separate.

When the tail light and break light are on the same bulb said bulb has 2 elements, one for the break and the other for the tail light, one element is burned out. Replace the bulb. If you've replaced the bulb, it might be the wiring. The holder for the bulb sometimes is at fault. They are $40.00 at the dealer, but at a pick a part or salvage yard they are $2.00.

It has a tail light which does not get brighter when braking.

the 1989 Honda accord lxi has a brake lamp light on the dashboard, if the brake lamp light is on, this means you have a brake/tail light out or disconnected
