    Hello, friends. I have owned an e36 '98 M3 sedan for a very long time and never made any changes. I purchased some clear brake kits, side indicators and front turn signal lamps and finished putting them all in tonight. I was pleased with the look against the estoril blue and was happy everything worked with no check signals on the computer screen. I had been checking the bulbs by hitting the hazard button. Once I was ready to return the car to its normal parking space, it was dark so I turned the lights on and was disappointed to find that both the turn signal indicators on the dash screen were continuously lit. When looking at the car with lights on, all the lights are on instead of just the low beams and the rear red lights. I am guessing that there is something else I need to do to the circuitry in the rear brake light housing kit. I was afraid to mess with it, and was happy when I thought it would work as it was. I know that this is what I get for messing with aftermarket parts and trying to do this myself. I'm hoping this is a common issue with an easy fix. Thanks in advance for any help.

    Welcome to the forums. Can you describe in more detail what lights are on with the switch on and when its off. What kind of rear lights did you put in LED's or just like oem but clear turn signal?

    So when I turn on the light switch, all the lights come on at once. This includes the low beams, front park light turn signals, side markers on the fenders, the brake assembly lights that are on include the normal red tail light and the yellow turn signal lights. The brake lights are off unless I push the brake and the reverse white light is not on until I back up. I have in amber stealth silver-coated bulbs from www.bavauto.com. On the dash, the turn signal light indicators stay on and the blinkers cannot be operated. If I turn off the light switch, everything works normally for daytime driving. So I was assuming the problem was a relay in the new brake light kit, but from answering your question, I'm wondering if it could also be that the new bulbs are causing some sort of problem.

    Did not try to change to LED. Just the normal bulbs that fit.

    So, here's what I'm thinking may have happened: I put in the rear brake light housing and it should be plug and play. There is some mention about taking out a tab on the one driver side kit and a larger bridge on the passenger side kit. The note says this can be done if there is a check control function. However, it does not say that this must be done on both sides or else. I am guessing that because I did not do that step, something got damaged. I was hoping to put it in and if a light came on, then I would take the tab(s) out. Since putting the original kit back in did not correct the issue, I'm guessing that I ruined or burned something on the car when I first put the brake kits in. In the daytime with the original tail kit in, everything works fine except the reverse lamps aren't coming on. At night, all the lights come on and stay on including both turn arrows on the dash. The turn signals/hazards don't operate at night. Mr. Charlson89 thought I might have a problem with a relay unit inside the fuse box. If I take those tabs off (or keep using the OEM lamp kit), then replace the relay box (i.e. get a new one from BMW), will this solve all my problems?

    That is a hard question to answer as I am not diagnosing the issue. But the E36 lighting system is very simple basically fuse, switch, bulb, ground, relays that kinda stuff. There were no light control modules in this era. So as for the new tail light kits causing a short to damage something is kinda unlikely. Mainly because if they did short something out a fuse would have most likely have blown and the whole circuit would be dead, not staying on when they shouldn't be. As for the tabs can you tell which lights you bought and I believe you vehicle does have the check control feature since it's a M3? Me personally I would try a new hazard relay instead of the entire box much cheaper and less of a pain.

    Just thought of something you said you replaced the bulbs with new ones right? You go the stealth bulbs from bav auto? When you swapped the lights back over did you use those new stealth bulbs on the old tail lights and corners? If not try swapping your old bulbs into the new housing and let me know if anything changes.
