Not sure what is wrong with my halos in my ZKW headlights. My drivers side work fine. BOTH my passenger side SOMETIMES work and sometimes look as they do in the following pictures: (if one works so does the other. if one is out so is the other.)

Problem: most of the time my passenger side halos only do not fully lightup and their is a very faint glow in the topleft of each ring that is photoed

My troubleshooting.
1. I searched the forum.
2. I tested to make sure my line from the parking lights for the halos has power which it does.

Can anyone help? Thanks!

http://www.neoautos.com/images/lights/haloworking.jpg the other side lit up

Do they eventually go to full lighting after being on for awhile?

And are you checking with the car on or off?

Just put them in havent had much experiance with them yet. One day when I left work for home they were on when I got home and would light up right away when I turn lights on (motor running didnt matter) The other night however I put about 30 min on my car and they never did come on. Drivers side had no issues and were working fine right from when I turned the car on. The motor is not running in those pics but it is not differnt eitherway.

Here is a better picture. Anyone...

I had a similar problem with my Depos. When I called DDM Tuning they sent me new inverters, and that seem to do the trick.

halo's are problematic at best, ditch them

Cold weather, you either need new/different inverters or park where its warm.
