Fix for HID / Check lowbeam lights fix

CHECK LOWBEAM LIGHTS after HID Upgrade.

This is caused by the cars system checking to see if your low beam light circuit is closed meaning the H7 bulb's filament is still connected. If it is cut or burned out, then the check lowbeam lights kicks on.

If you have not replaced your H7 bulbs to HID then your low beam H7 bulb(s) needs replacement.

If you've upgraded to HID lamps from H7 bulbs then you'll get the CHECK LOWBEAM LIGHTS Message.

Since HID's use a ballast and the bulbs in HID's do not have a filament but xenon gas to eluminate the lamps, this causes the system to think the old H7 bulb is burned out.

You have few options, buy a resistor pack like the one pictured below that will fix this error message. Build one of your own which shows at the bottom of this page or use City Lights to resolve the problem.

A similar resistor pack can be purchased from hid4less.com for $139.99*

* Price quoted off of their web page as of June 2002 shows they have the Hella resistor packs.

To order the resistor pack, click on the 139.99 from the hids4less.com's web page

Another Option is to install City Lights to your low beam head lamps.

Gene,

To install a city light kit to eliminate the check low beam you need to do the following:

If you have factory headlamp housings you may need to open up the holes at the top of the high beams. It is marked, just not knocked out - carefully drill through the black platic housing. If you have replacement lights the hole will already be there and plugged with a gray plastic plug.

I tried several different light sockets - the ones that worked best for me were from the side fender mounted turn signal off my 1994 E-34. The dealer should be able to help you find the right size - places such as Pep Boyz have nothing that will work. These sockets hold standard size 5 warr marker lights - I think bulb #168 or 194? - you can use either clear or amber to your preference.

Just splice the wires for the city lights into the wires for your low beams close to the headlight unit - and no more check low beam warning.

The most inportant thing is that if you do have to drill the hole in your housing unit be careful doing it, use a drill bit that does not have a course thread because it can catch an edge and break off excess material and the socket may not fit securely. Probably if you have access to a Dremel tool to bore out the hole that would be best.

If you need pictures or anything let me know.

Hope this helps,
Roderick

Fix for Xenon Upgrade
By "Lefty"

One of the problems with upgrading from to the OEM or factory Xenon lights in your NON-Xenon BMW is that it causes your computer to post a "low beam" failure message. The other problems is that there is no self-leveling on the Xenons. In the following post I have documented how I have fixed the dash warning error message about the low beams. The problem comes from the fact that the Xenon light assembly does not have any resistance when turned off, thus resulting with an error message.
