Default Rear taillight question.

Ok, I live in the Northeast and drive a TON for work. I have a white car, and well it blends in, in the snow. What I would like to do is simular to the carry over option many european cars have, brighter taillights for bad/snowy weather. Instead of wiring up new sockets and bulbs, I would just like to brighten up the portion that is on the trunk lid area.

I am assuming that they are 194 bulbs in there now. What if I changed it out with a different bulb that burned brighter? I have done this with cornering lights on other cars, but will this screw up the bulb monitor system?

Im not sure how the monitoring system works, but a lower resistance bulb (brighter) may not set off the system, because it looks for open circuits, not low resistance.... Don't quote me on it though, Ill let the experts take this one

I think the adaptive light (or maybe lamp) module measures resistance. Search the module name, We talked about how it worked somewhere.

I replaced the the side marker 194NA bulbs with 3652 bulbs on my car.

It'll only cost you a few bucks to try and see if it works for you.

Well, here is what I did. I replaced the 194s that were in there with 906s. I did this with the car in the 'on' position and lights on. When I put the last bulb in I then heard the bulb monitor go off about 5 sec later. Long story short I have 906s in the inner most spot. Not the exact results I was looking for, but the 906s burn about 2x as pright and really illuminate the light bar nicely. It really makes the rear of the car more visable at night but does not look awkward.

I really liked how it looked with all 906s in there, but the blub monitor would not play ball. BUt is it better.

The bulb monitor is reacting to a change in current flow as compared to what it "knows" it should be measuring on that circuit. It says the bulb is blown because, well, it can't say anything else; it doesn't have a different message for an _increase_ in current flow. The warning should go away after some number of driving cycles as it learns the new behavior of that circuit.

I would be careful that your more-powerful bulb isn't going to melt its socket, though. Keep an eye on it for a while...
