I loved my DDM's untill they started causing problems like, driving home at night without the lights on. And I don t think the color output is the best. Check out my group but, if we can get the kits in the low $200 for high quality, bulbs, ballasts and projectors there will be many happier customers.
Also keep your stock bulbs with you in case a ballast goes out or both. I had to drive home one night with my fog lights only, thank god I was only 2 miles away.
I still like my bi-xenon retrofits a million times better then the DDM's I had, but the OEM quality, performance and output by far makes the retrofit WELL worth it!
All the times I tried to have them replace the ballast, it worked fine when I got there. I'm just saying that the extra time and better products I got make my headlights blow away any other manufactures OEM setup. I have zero issues with ever thinking about my lights not turning on, where as with the DDM's and the wiring harness, I would still drive home with one headlight on and not even know it till I pulled into my parking spot.
