bi xenon is crap and nothing but problems,
Lifetime warranty is bullcrap, they just say that to get you to buy the product then when u have a problem then they make it look like u did soomething to void the warranty...Go with a company with good reviews and a set time warranty... think about it why would someone want to replace your kit for life... lets be realistic....go with my recommendation because of my expierence that I have had with my kits...
thehidfactory.com
has good reviews if you just type them into google u will find great reviews...
ddm has terrible customer service and they have a fraud a** lifetime scam like all the other companies that give u problems when the issue arrives..
