I had swapped out the weak stock woofer in the 2gs3 and put in a 10" Eclipse subwoofer with a Fosgate amp. I couldn't just stop there I took out the 4" speakers and put in 6 1/2 Focals all around with another Fosgate amp for the highs. Lastly put in a capacitor so my lights won't dim while I am at a stop. It sounds much better now. A little bit of a rattle but I can live with it. I will look into dynomating once I can find the time. After I was done I had the shop change out my license plate bulbs with ones that I picked up from EBAY... That is when I got a sensor light to turn on the dash. Have any of you guys had that problem how can I fix it if not which ones can I use that is acceptable and will not trigger the annoying light to turn on the dash? I really like the LED style license plate lights similar to the ones on the newer IS.

Here is the amp set up with capacitor

Update figured out the problem to the warning light signal on the dash due to a bulb being out on the 3rd brake light. Wow.... CL is very informative.

 

You gotta give people a little time!

Like you found out, the dash light has nothing to do with the license plate lights, glad you got things figured out.
