That first LED light design is brilliant in multiple ways. I recognized that the metal, being reflective, would also act as a light reflector to increase the actual light output. Then it is non magnetic, so most likely not going to rust. Also, no solder joints, to fatigue over years of bumps. It truly is a marvel! LumiLEDS really created the perfect automotive LED light assembly. At least in my opinion they did. Thanks so much for sharing IMSAI Guy! Fred
2000 Deville, 1st car w/ all LED rear lamps Flat part contains all the pieces that fit in the black carrier after stamping and folding 4” round is for truck and commercial vehicle applications
1:30: the operation is staking (it may also be classed as riveting). The metal could be a number of things- austenitic stainless, like the common type 304, is non-ferromagnetic. Some grades are quite ductile (304 is used for safety wire in aerospace and auto racing) , common, and reasonably inexpensive. Pure nickel is ferromagnetic, but many nickel alloys are not. If you know someone with a PMI unit, it is easy peasy to find out.
I think this is technically considered clinching. Staking is deforming a shaft or boss to form a head, whereas clinching uses a punch and die with 2 flats sheets of material.
@@mgobluevictor It may be a clinch. I went with staking as it looked like the deformed section went through a hole in the substrate, and that is the term I am familiar with in the industries I work in for this use case.
The magnet test is not a reliable way to test for stainless steel. There are also magnetic stainless alloys. I think nickel or nickel plated brass might be more another possibility.

Very cool video. I replaced the 12 bulbs with a similar assy for a Mini.
I think the metal is Nickel. That's what is used to connect cells in battery packs.
Looks like it.
Neat. I like the fixing method.
It's another type of riveting!

feels like its been ages since that video
LEDs on the side is the "marker light."
Are those multicolour LEDs? At 2:31 they don't just get brighter between tail & turn, the turn LEDs appear yellow, at least on my monitor :)
no, the camera did that

When I look up a Cadilac CTS tail light, it rings in at just under $500. The good ol' days of replacing a $2 light bulb are gone.
I had a Jaguar S-type and the car wash ruined a headlight. Cost them $800
OK, this VID was a big tease if you wanted these LEDs. Because you CAN'T ' have them.
STAKING. Like steak-ing.
Cool. Thanks for the look.
