gary10 Posted December 17, 2014 Share Posted December 17, 2014 Hello. I have a 2003 Lexus GX 470 and would like to replace rear tail/brake light bulbs for LEDS. I have purchased some # 7443 on ebay but for some reason it doesn't work. i was doing 1 side only. I have inserted 2 bulbs but only 1 works and only for parking and not for brake. Anybody had any experience in it? Thank you in advance. Quote Link to comment Share on other sites More sharing options...
VBdenny Posted December 18, 2014 Share Posted December 18, 2014 I'm not sure you can just change the bulbs. There may be some kind of transformer needed. I know the kid next door had a big issue with the bulb change. Quote Link to comment Share on other sites More sharing options...
