rear is suppose to be anywhere from amber to red in the back turn... but i have the red/clear tails for 6th gen and left the stock clear bulb in my turns.. it kinda looks yellow in the daytime and at nite it's sorta clear but still sorta yellow.. i noticed on some volvo's.. they seem to just have a stock clear turn signal bulb that flashed almost as bright of a yellowish light as mine.... i passed texas inspection august of this year in travis (austin) county.. and the previous 2 years in collin (plano) county with my clear turn signal bulb.. yeah.. unless an officer really wants to be a dick.. should be aite.... oh.. btw.. pep boys sells the M3 (7440) bulb u need for ur rear turns in orange, red and hyperwhite made by apc = ( for 4.99 a pair...
