Well I bought me some polargs cuz I saw that everyone pretty much had them(imma noob) and I put them in and I dunno If im too impressed or not, the size of the bulb I got was correct, but did I get the correct model??
This is what I got:

 

they are not impressive at all i had a pair and didnt notice a difference im very happy with led bulbs i bought on ebay

 

led is the way to go.... everything else is not as bright.....
