rear driving lights/brake lights LED problem

ok, bought some led lights last week and got them today, put them in and turn signals work great..but the brake light/ driving light combo isnt working right. when I turn on the lights it lights up fine but they are too bright and there are no brake lights. I pulled the bulb from the housing and watched the different lights go on...Im thinking I got the wrong bulbs??? I got the ones according to what was suggested to me from here...I'll look at the model tomorrow.

Did you buy bulbs or whole led assemblies?

If whole assembly, you may just have the brake and running lights switched

bought just the bulbs. Turn signals work great...the red tail/brake light works as a brake fine as long as I dont turn on the lights...once they are on they shine bright and when I hit the brake there is no change. I reversed the wires thinking it was a polarity issue but still the same problem

Do standard bulbs work correctly? If so then you are somehow putting them in reversed or the bulbs are incorrect

Or terminals in light are damaged causing bad connections....

You might have your brake and running light wires switched. So brake lights are on all the time... sorry..sounds like you tried that

This doesnít make any sense. There are three leads for the tail/brake lights: tail, brake and ground. If you look at the base of the bulb, there should be two contacts that align with the two spring loaded contact in the light socket. These are the tail and brake +12v connections. One goes to the bright filament (brakes) and the other to the dim filament (tail). The case of the bulb is the ground. Switching the tail and brake leads is not switching polarity it is switching the signals. It sounds like the tail lights are connected to the bright filament. An easy way to check is to disconnect the tail light signal and depress the brake pedal. If it lights dimly, you found your issue.

One technical note, I realize LEDs donít have filaments.

The bulbs fit only one way due to the little prongs being offset. If the regular bulbs were working the wires aren’t crossed. I think your led bulbs are either just crazy bright or they are faulty

I checked again...I used the regular bulbs and the sequence worked fine..then put the leds in...They must be the wrong ones. I'll call the company or email them and explain the situation, hopefully I can return these ones if not just get the right ones

Did you look at the base of the bulb and verify there are two contacts?

That's the wrong type of bulb. The white/yellow bulbs are designed for combination turn-signal/parking-running lamps.

You believe you want red/red 7528 bulbs.
