Just did my 3rd WK2 over the weekend...16 bulbs (including 4x reverse and 4x vanity). Install takes less than an hour, and now I could do them all in 30 minutes.
Bought all of my bulbs from XenonDepot (vendor on here)...great customer service and product warranty! Contact Danny or Steve and they will take care of you...JeepGarage members get a discount too!
And on the over-heads that cannot be replaced PNP, they are not nearly as "yellow" as all of the other stock bulbs and I do not even notice the difference unless I look straight into the lights. The LED's are so much brighter they "take over" the over head!
