I bought a new diamond cut headlight with a blue tinted bulb awile ago. Shortly after I saw condensation on the inside lens & the light coming out was horrible.
So I pulled the headlight .....
Pic) hard to see but condensation on inside lens
2)The rubber boot had melted somewhat
& you can see the corrosion from the moisture
3) Again hard to tell but the aftermarket bulb leaves a 1/8" open gap around the bulb flange
4) The stock headlight bulb & headlight case mounts nice & flush. As it should.
Moral of the story BUYER BEWARE. Blue tint bulb sucked. Stupid me
Note: Blue tint bulb was also a 55/80W
Hence the melted boot.
