I installed mine and they light up with the running lights, but don't get brighter when I brake. Any suggestions?

Check your connection. unplug them and re plug them and try to listen for it to snap in place or feel if connects Same issue I had on one of them It didn't conect all the way and make sure they look wired up correctly as your old one if no return for new ones

They only light up with your lights being on. Bright Tails makes an alternative that lights up with brakes and turn signals, though.

From description: For the wire line, black-- main line, yellow-- turn light, white-- reversing light, green--tail light, red--brake light. You only have 4 wires on these LED's or your existing vehicle/trailer wiring? If you're missing wiring on these LED's I'd suggest contacting the Manufacturer. I'll assume you're installing these lights on a vehicle/trailer with the wiring described in your question. 2 wires for turn should be for left and right. One to each of the LED's yellow wires (your existing wiring may vary but typically from vehicle yellow=left, green=right). Same goes for "2for backup" (1 wire to L/R side of the new lights white wire). You should test voltage on your existing wiring to determine which of the "2for brake" wires is tail (lower voltage) and brake (higher voltage to be visible when taillights are on) or add an inline resistor to your existing taillight wire to reduce the taillight signal (green) so the brake light will be visible when both are on. Im not 100% on this but you may be able to simply wire the LED's brake and tail wires together (green/red) if your source varies output voltage via a brake switch or similar. Black-main line I believe is ground connection. Also check that your flashers work correctly (if applicable) as LED's draw very little load and often do odd things to flasher relays. Hope this helps. Good Luck

There are wires.I cannot find my notes but somewhere in the comments on these someone tells exactly which is turn,run and brake.Simple to wire and very good lights with excellent visibility..White wire goes to ground ( any metal surface will work). This goes for both lights. ****White wire from trailer connection also goes to any available ground. Black wire is for your running lights. ****Black wire from both lights goes to the brown wire from the trailer connection. Green wire is for your turn signal and brake lights. Connect correctly the brake lights will also work. ****One green wire from the lights goes to the yellow wire from the trailer connection. (The right turn signal) ****The other green wire from the light goes to the green wire from the trailer connection.(The left turn si

They should, but don't work for brake lights / running lights because there arent 2 stages of lights. Mine burned out quickly, I think because of wiring

I bought these in dual filament 7443, yes they work. However, the brightness between the two filaments is not as apparent as the OEM bulb. I would say when the brakes are applied the OEM bulb is twice as bright, these LEDs are brighter than OEM when running, but when the brakes are applied maybe only get 20% brighter. Not too much difference...

perhaps u connected to the rear running lights rather than the rear back up lights

I bought em. They go in and fit with everything. But uh I have weird issues with them. Like my little turn signal light that doubles as a driving light goes out if my I don't turn on my lights full tilt. They are supposed to be on all the time. And one of them doesn't stay. So idk whether it's just my lights or that they are all like that.

There is a small internal device that acts as a starter to make the bulbs light up. It sounds like that starter has gone bad. Contact Flowtron and send them the unit for repair.

I'm also having the same issue with 2 888LM's keeping the lights on constantly. They didn't seem to do it when first installed but nowall the time. I'm wondering if they get more sensitive during colder temperatures.I've turned the motion detection off for now unfortunately.

The brake light module works on all brake lighting. I tried it with a regular and LED light. Both work just as well. Remember though by making the bulb flash more often than usual bulbs or LED's go out sooner than later/called over usage. Everything has a lifeline. I drove around today and I tell you people sure take notice to the flashing third light. the majority stayed off the rear of my vehicle. Good luck

Just follow the instructions without cutting open the actual light http://clubsciontc.com/forums/diy-install-guides-23/diy-full-third-brake-light-18128/

Also when you removed your old bulbs from the factory plug, pay attention when plugging them into the new harness. Make sure the black wires going into the back of your factory plug and the black wires in the socket of the new tail lights are plugged in the right way so that the black wires are connected together correctly. If not connected black to black, the tail light don't light up correctly when pressing the brake pedal.

Mine don't stay on, buy I've noticed that they aren't very bright either..... led lights use less power then the factory incandescent style, maybe there's a constant voltage going to them that isn't enough to illuminate the factory lamp but is enough for the led? Just a thought

The bottom lights are only going to work when the brights are on as those are the brights. Top are the low beams. It would be very foolish to wire them to stay on, you'd have a lot of angry drivers and there would be nothing you can do about it.

I'd check to make sure the wires are correct. The colors were not compatable with the harness in the Jeep so I had to figure it out on my own. Make sure that the ground wire is secure too. I also had to install a new flasher control (under the steering column cover) to compensate for the lower draw of the LEDs. It would flash very quickly. I'm very happy with them.

These are dual element style lights which means running lights and brake lights they use same negative and different positives it's been a while since I wired it so couldn't tell u which is which but I checked by touching the battery directly found which side was brighter and tied it into brakes other one tied into license plate light done deal
