Long term follow-up...
The lights still basically work, but one is now considerably brighter than the other, or the beam pattern is diffused in such a way to make it appear less bright. Oh, and anyone in front of me at night hates me.
But they see me.
I'm thinking of trying the Harley fog/driving lights from the same source later. The set will cost around $95 as opposed to [email protected]
$17ea, but that's still not bad compared to a set of Denali's.
