The lights are these:
My Hella Lights :: HELLA 500 Black Magic with the yellow protective films.
The mounting was really quite ghetto, as you can see here:
A screw from inside into the top of the plastic ensured that it stayed upright. (Told you it was ghetto!)
But last fall I began my project to embed them into the bumper with fibreglass. I cut out an oval at the top, to get them as far into the bumper I could, but had to make sure it didn't get too far in and hit the metal bumper inside. While also getting it as close to vertical as I could. Then I fibreglassed around the headlamp while it's in place. Adjustable? No...
But I had to rush the painting (as you can obviously see) due to low temperatures, so I desperately need another paint job in the spring. And I will do the finer edges and improve the filler before the new paint.
They are low and don't cast much light on the road, but hey! It looks cool!
