Started with the M5 pre-01 clears to get rid of the amber signals. Then went full Celis. They make the car look updated and they're really bright at night. Here's the full install.
The car as it was before the Celis lights. I had already installed the rear clears from the pre-01 M5 to get rid of the amber signals. I do like amber signals on some cars, especially green ones where they provide great contrast. My preference for Titanium Silver is clear.
A comparison of the two lenses side by side before installation. The difference in the LED arrangement is immediately obvious — the Celis units are far brighter and give the rear a much more modern look.
These are the instructions provided within the Hella kit. Four pages. Read them. Seriously.
There are four bolts you need to remove to gain access behind the lens. Once the lens is out, you'll see the section where you need to drill.
Removing the lens exposes the section where you'll drill. Images for this step were taken and edited by AlexPS. The finished product shows where the new holes are drilled — these are the mounting points for the LED lenses.
Both sides done and ready for installation. The ballasts included with the kit take up some storage in the wheel well. Some don't like that — you could fabricate custom brackets and mount them wherever you wish. The duct tape was an idea from AlexPS; I followed his lead there.
The lights work! They are much brighter — even the turn signals are pretty bright compared to the older style. Mostly, I like the updated look. Back home and all buttoned up.
