The Delta Lights guy is on the forum. Doesn't seem like he cares to help though....hmm.
I'd say get your money back and buy a better product from someone else!
He hasn't been around much, he got a pretty rough welcome if I remember right.
The Delta headlight upgrade is the best bang for the buck lighting upgrade I have found yet.
My kit was F'd up, but I blame 4WP more so than Delta.
Delta immediately sent me out the silicone rings and did thier best to make things right.
If you know of a better product anywhere close to the price, I'd like to hear about it.
Near as I can tell, the only other full upgrade I know if it piecing one together from Daniel Stern and you end up with more money and it's not plug n play.
His Cibie upgrades are awesome to be sure. But more money and more work.
I like dropping $100, doing a 20 minute install and getting good results.
Like I said, not trying to pimp Delta, just stating they took care of my problem and I'm happy with my results.
