Hello. I'm new to the forum. I purchased a 2012 srx performance. I've already done a few mods ( led interior dome and courtesy lamps, laser ghost entry lamps, 2015 grille, etc.) I would love to change out the rear signal lamps for some leds , but not sure where to splice and mount the resistor needed for the mod.( not a lot of room behind the housing.) I would also like to change the drls and signal lamps in the front, but I think I will wait until one of the regular bulbs fail, because it sounds like a pain in the ass to gain access to them! Any info on these mods by someone who has done them would be great. I don't Know why GM didn't integrate the rear signals into the brake lights. That would have been a great improvement. Oh! by the way! Love the Caddy! (2012, performance ,Mocha Steel, Shale w/Brownstone int. 46k).
