You'll need to undo the top bracket, the screw holding the indicator in, slide the indicator out carefully which exposes two nuts on the side of the quad holding it in. Then undo the grille and carefully remove the light!
Proper weird that, I've been after a Passenger side quadlight and slam panel for a while. I recently got a new quad from corsagsi2000 and Slam panel from Toyota through Gary GBR, so it probably isn't mine..unless someone wanted to spontaneously give me an unexpected xmas pressie lol
I've got a Whiteline myself and can't recommend it enough! Gets rid of the wooly stock feeling and makes the steering a lot meatier, but not heavy! The improved feel inspires a lot of confidence in the corners, brilliant mod! Easy to fit too, the only tricky bit is getting the old bush off the wishbone!
I wouldn't get the LED ones for indicators, if you want to you'd need to wire in resistors to make them flash and I don't have a clue on that tbh! JDM wiring guide
