Just letting you know the Capacitor mod does work for HID's

For anyone looking to upgrade non HID lights to HID, the Capacitor mod works flawlessly.

My 2008 528xi did not come with the adaptive lighting package so I ordered a kit from DDM tuning with the Bulb out warning cancelers, but they were back ordered on the BOW. I installed the lights without them and they worked fine for a few minutes, until I drove with them on. They would be fine driving on the highway, but when coming to red lights or stop signs they would flicker like crazy and you could hear a awful sound coming through the speakers of the car. I couldn't wait for DDM to Ship the BOW cancelers so I went to radio shack and made my own with the DIY. Worked perfectly. No more flickering or buzzing. Some say their capacitors blew, but most likely they reversed polarity when installing them. I soldered mine in and used shrink tubing on everything and it works without a hitch.

Pretty much what mine look like


Just FYI, I got the 55W 5K. My phones camera make the light appear bluer than it actually is in person. Cutoff line is still sharp with the projectors and produce a nice rainbow.



Just thought I would post this for anyone looking to upgrade their lights since I couldn't find too much specific info on the topic pertaining to E60's. Works on HID fogs as well.

Speaking on the fogs. How do you get to those bulbs. I look underneath the car and I couldnt figure it out

There are a couple of different ways you can get to them. When I was swapping low beam bulbs for HID's, I removed the headlight and I could see the fogs lights clearly from above once the headlight was removed. Another method is going through the wheel well.

I personally find the headlight removal method easier just because I've taken them out so many times it takes me less than 2 minutes per side and you have all the room you need to change bulbs, add HID or whatever. I feel the wheel well method only gives you limited access.

Cool. Thanks for the directions...Im going to go try it now...One more question when you bought you HID kit from that site did u also replace the halo bulbs too with HID and what color temp did you buy. I want a white look so I was kind of looking at a 6000-8000. My car does have the adaptive with Xenon lighting. I just want a different color for my halos and fogs

I didn't change out the halo led bulbs. I'm fine with the way they are for now. If you're asking what color HID bulbs I put in, they're 5k. Any higher and I think they're going to be blueish.

Yes 5K is good in my experience with changing HID for my other cars. My car comes (535I) with adaptive HD low/high. I am trying to change my fog light to HID. Currently I have ordered with DDM tuning for 55W HID (5k color). I am planning to change my Angle Eye with HD also.

Will this work for a 2004 BMW 645? I just installed DDM tuning HID fogs, but they keep flickering or they turn on for a sec and trun off.

I didn't know you could replace the fog lights by taking our the head lights. Thats genius. I'm going to try that now. Thanks!

Worked great on my 08 550i Thanks

When I did my fog lights, I chose a CANBUS Ballast which does away with the BOW canceller. I used a 3000 degree bulb for the yellow tinge for use in actual fog. For the driver's side, I had a difficult time getting the bulb into the fog light housing due to the windshield washer reservoir, so I had to also turn the wheel to the right and install the HID bulb through the wheel arch liner.
