Here is the stock position.
Here is the new position.
You just cut it at the same 45* angle, a little at a time, until the bottom edge of the plastic mount lines up with the corner of the aluminum bulb housing.
Now when you compare it to a stock bulb you see they line up perfectly.
Since I can no longer use the little locating screw to hold the black mounting ring to the silver bulb I was worried the double o-rings would not be able to hold the bulb in position over a long period of time. It might rotate or slide backwards a little messing up the beam shape. So I used some rtv silicone between the 2 pieces were they meet up at a 45* angle. It's strong enough to hold it in place, but I can still muscle it off later if I need to.
The factory beam shape is no where as good as a projector, but as you can see, I'm getting a factory shape. Even at iso 100 and the exposure turned way down on my camera the led hot spot is a bit over exposed and blown out a little.
Here they are mounted. For cooling they use a copper braid that you stretch out. It's coated with a silver finish to prevent tarnishing.
I might rig up a simple tube to catch air behind the grill to direct on the braided heatsinks. This might improve longevity. Then again, this braided style heatsink might be much better than the ones from my older kit.
Oh yeah, this kit gives me good high beams as well! No more scattered high beams like the old kit had.
Using my lux meter I measured 4 times the output over the stock incandescent bulbs. The stock bulbs meadured 700 lux and the led kit measured 2700 lux. This didn't surprise me at all as it's much brighter than stock.
The color temperature of this kit was a surprise as well. My previous led kit had a light hint of blue to the output that washed out colors a little. This kit doesn't have that blue. It doesn't have any yellow tint either, just a nice white that seems to render colors accurately. Eh, maybe greens are a bit faded, but not too badly.
I'll update this post with some night shots that show the beam shape and color rendering soon.
