**Im writing this review 2 years after the intial purchase and use of the Delta Quad Bar Xenon boosted headlights. Just ditched them for LEDs
Face it - stock headlites are terrible!!! I live in deer infested WI so I started looking for something better. Found the Deltas. I liked that I could swap out bulbs rather than the whole lamp. When I got them - 100% better than stock. BUT
, since stock was like having 2 candles lighting your way, it left a lot of room for me to be "impressed".
The actual lamps fit very snug - only allowing me to get 2 out of 3 bezel screws back into place. The plastic ring on the lamp got marred by the torx screwdriver because of how little room the lamps left.
The blue tint of the xenon boosted bulbs got old quick - especially in winter or rainy conditions - you couldnt see a damn thing! Luckily I had IPF driving lights to make up for it. If you dont have secondary lights, you will probably end up in a ditch.
So, I swapped the Delta bulbs for Sylvania Ultra Whites - which were awesome. Again nice to be able to change bulbs... but when I dropped $130 on lights - I want them to work without having to drop another $40+ on better bulbs.
The housings are not water tight so if you do a water crossing/car wash/driving in the rain, you will get condensation inside the lamps.
Another thing I absolutly HATED about the Delta Quad Bars was the Googly eye effect. The actual plastic quad bar has a black center cone that covers the bulb. The reflection of that plastic cone creates a googly eye when the lights are not on. I **** you not the eyes follow you when you walk buy and made the Jeep look comical and dopey.
This was 75% of the reason I ditched them - some people probably dont notice or care - I did and it drove me nuts. *See Pic, one of the only pics I have of the googly eye since I would do my best to never get it in photos*
Overall, I would urge you to look at other options. As a new Jeep owner who only knew of what was in a Quadratec catalog - I ended up spending $200 over the 2 years I had these. Thats $200 I could have put towards LED or other top end lighting.
