Tail chop performed, brake light doesn't work

Only wires not altered in the procedure and only one with problems. Tail light works fine but doesn't brighten when brakes applied, either by pedal or lever. When I switch the hot leads on the light it is brighter. Possibly a bad relay? There is obviously power coming from the regular tail lead but apparently not the brake lead. Any other suggestions? Fuses fine. Bulb replaced.

    The problem isn't that the light doesn't work at all, I do get the tail light. It just doesn't brighten for the stop light. I've checked the switches, I've checked continuity on as much of the wire harness as I can access and everything seems fine. I've also changed the bulb. I even get power from the brake light lead but the light won't work. I've checked every connection I can find. I'm stumped so I just ordered a new LED taillight with integrated signals. If that doesn't solve the problem I'll post back. Thanks.

Hi,

Offhand, in most bikes, the tailight and the brake light are integrated in a single bulb with a common ground. This would translate then into a 3wire arrangement. The brighter of the filaments is for the brake while the dimmer of the two is for the park/running/tail light. To my knowledge, either the tail or brake lights do not use a relay, they are wired straightforward. Your described problem all points to a mis-connection, possibly the ground wire. The easiest approach would be to identify the ground wire. With ignition switch off, all light switches off, identify the ground wire with the use of a continuity tester (VOM/DVM). Disconnect the wires to the harness, on the harness, it would be the wire with nearly 0 resistance against any exposed metal or the chassis. On the wires going to the tailight assy, it wold be the wire that measures 0 ohms to the metal socket/housing of the bulb.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

I have an 1100 V-Star Classic, the brake lights are not working. I have replaced the bulb but still nothing. The running and turn signals are working fine. What is my problem?


Check using the voltmeter if you are getting any output in the bulb holder? You might also need to check the wiring that connects the bulb holder to the main base wiring. Since the turn signals are working fine, there seem to be some problem with the wiring connector that connects the tail wiring with the main one. It might be loose or damaged. You might need to check the condition of the wire that connects the tail lamp to the holder as well.

I would start simply.Check or replace all your bulbs first.Then take apart your bulb sockets front and back and spray with electrical contact cleaner and a little lubricant.Make sure all the sockets have free travel and are not corroded at the grounding points on the frame.Some lights ground through the frame mounting and some have a separate ground wire.It sounds like you may just have a bad connection. Most brake lights wont work with key off as there is no power to the circuit.Also clean your brake light switches in the handlebar and down on the frame for the back brake.

My tail light works fine but when i hit the breaks it doesn't brighten up everything is connected and i'm stumped.


Check the light bulb. Chances are that the brake light filament is burned out but the running light filament is still good. If the bulb checks out okay with a multimeter, check the brake light switch and the wire connectors..

The only switch on your tail light is the ignition switch. Any time your headlight is on, you tail light should be on. Check the bulb first as this is the most common problem. If it still doesn't work, check the contacts in the socket. Next check the wiring.

The tail light and brake light don't work. the bulb looks fine and the tour pack light lights and turn signal lights work.


The wiring sub-harness for the tail light assembly could have come unplugged, It usually plugs into the main harness under the seat or down beside the forward part of the rear fender. Also the wires could have been damaged under the fender back behind the tail light assembly.

Good Luck

Problem with rear tail light/brake light


Resolution Below -

Okay, I had the same problem...My 04 Suzuki DR200SE tail light /brake light is not working. Brake lights works in park mode not in ON with engine running or not. Tail light not in either mode.

Volt meter shows the socket is working correctly, fuses are good. I even adjusted the pressure switch for the rear brake application. MOM shows nothing positive to help me trouble shoot and neither does the internet. Lots of people with same issue, but I'm not seeing any resolution.

I'm posting the resolution as lots have had this issue, but no one has posted how they fixed it. It's the ground wire inside the tail section. Which is why the volt meter (which is grounded) shows the socket is good. You'll have the pull the tail section and note the ground wire has either broken off, or the wire has sucked up inside the insulation. You'll need to strip insulation, get to good wire and reattach it. I'd even solder it to keep it solid. Hope this helps someone else!!

Check your trailer connector, you have a short circuit between the brake and tail /marker lamps. or water in your tail/brakelamp. Also check both brake switches, for water or corrosion.
