Subject: Just installed auto headlight control. Long. Author: az735i : member since January, 2006 : 455 posts Posted on: 2007-10-19 01:33:53

I've wanted to do this for a while. I was able to find DEI Nitelite on eBay for less then $50 shipped. There is photocell that controls on/off for the headlights. It has daytime running light control built in. Install is not hard having the proper wiring diagrams.


This is the Nitelite system.

I chose to tap into the wires that go into the headlight switch. I used the Bentley wiring diagrams.


Under dash picture. The big connector in the middle is the headlight switch connector.


Close up of the connector.


I chose to install the photocell on top of the center dash vent. Here is a picture with the vent removed.


This is how I routed the wire.


This is the on/off switch for the system. I think that this type of switch looks out of place in a BMW so placed it by the hand brake.



Some of the wire connections. Wiring is pretty straight forward.

It took me a couple of hours to do.

Some misc. pictures of the car. Yes it does need a paint job. Hopefully I'll be able to get it done next year.
