So I've had my DDM Tuning HID head lights in for 7 years , after power washing the engine bay last week in readying for a show , I lost both head lights. So after some trouble shooting has to be a bad relay that is part of the system, I had bought two kits so as to have extra parts ,been on my parts shelve for the last 7 years , thought was to change out the relay, wrong both kits have one connector that is dfferant! So changed out all, one light not working & problem with high beam! Called DDM will see what they can do for me!! Needs to be fast as next show 3 weeks out!
You check the connections on the relay socket? I had a similar problem on mine and it turned out to be corroded contacts
2nd kit is working fine,changed the grounding point! Have to send the 1st kit in, they will replace all not working . I asked that the replacement parts match the kit now in use so if a problem I can swap parts ,as my original plan !!
