Hi Cape,We actually did the upgrade to the '15 lights as well and we actually went a step further. We had the drl stay on the whole time at 100% full on mode even at signals. We also have mirror leds so if the oncoming traffic dont see your turning signals then you shoudlnt be driving. IMO the leds do not outshine the turning signals als because theyre different colors. Wanna make the ambers even brighter? Vleds.com and get the tritons v3's... Thanks me later![]()
