I have a 2004 Bonneville an can"t figure out how

SOURCE: DASH LIGHTS DIM WHEN BRAKE OR LEFT BLINKER APPLIED

Pull the bulb out of both left side turn signals and check the filaments. As these are double filament bulbs, sometimes the filaments break and lay across the other creating a feedback issue.

Hi
First check that the new switch is an EXACT match to the one you removed. There are a number of different switches that will all fit on to the column, but do not match exactly.
Re check that ALL the plug connections are fully pressed into place.
This is usually the problem and is an easy error to make
Good luck
