The LED turns green when pressed but I can't figure out what it does. Maybe something to do with the alarm system? Thanks in advance. Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted December 27, 2019 It's watching you... Not sure, but it isn't factory. Is that a little picture of a sun? Does it turn on some aftermarket daylight running lights? You may need to play with light switches to see. Perhaps some "cool" under car LED strips? Just a guess. Quote Share this post Link to post Share on other sites
AndyC529 0 Report post Posted December 27, 2019 Yes it is a picture of a sun, you might be right about some aftermarket lights. I'll have a look tonight and see. I just found a hidden Sprint Booster button under the dash as well so I thought it might have been related to that somehow but I can't find any similar looking modules on Google Images Quote Share this post Link to post Share on other sites
