I own TWO BMWs... and thus have the need to replace 4 Angel Eyes. Having replaced two already in my wife's E61 and spent $90.00 in the process for their holders...I decided to find a workaround and NOT have to spend $45.00 for a bulb replacement. Its ridiculous.

I did this more out of principal since BMW charges so much for these units... without allowing us to simply replace the bulb. Not to mention its a total waste to throw away the bulb holder.

This will work for any Angel Eyes.... as far as I know.

What you will need:

A Dremmel

New Bulbs:
I successfully used the Osram - 12V 10W Mini SC Bay (BA9s) Clear - which is a DIRECT replacement for the Phillips bulb. In fact, Osram also makes parts for our headlights. They are not some cheap brand.

I HIGHLY RECOMMEND this place. FAST SHIPPING, VERY NICE PEOPLE too!

Tools (Torx bits...) and ability to remove the headlight or access the Angel Eye (I suggest you use the forum on how to gain access for your car)

Cleaning Cloth

Once you have removed the carrier, take a very small dremmel bit and make one notch. It will have enough room to take it out. If not, you can always make another small notch on the other side. you wont need to take off much material since the pins on the bulbs base are very small. Just enough to slide it out. Don't go hog wild... just enough to cut the slot... and do NOT go deep. Take your time and be gentle. Remember, SMALL BIT. You can see just how small the pins are in the pictures.

Install the new one, but do NOT TOUCH THE BULB. The oil from your fingers can cause early burnout. To install, just slip the pins past the notch, gently wiggle it around in the carrier until you feel it catch, push it in as you gently twist.

I did NOT upgrade the wattage. I have read too many issues where it melted the carrier. I am keeping it totally stock. Best to play it safe when it comes to our headlights since they are stupid-expensive.

12 VOLTS and 10 WATTS.

To remove the bulb, simply push it down and twist.. you will feel it come out of the base. Very simple.

See the attached picts for visual help. If you are in the King of Prussia area, I may be willing to help you...

And to think you have just saved a LOT of money for a stupid bulb. Sorry BMW.... some things dont need to be over-engineered for profit reasons.

Btw, this is at your own risk, of course. This is just my little contribution. I hope it helps someone.
