8" H4 LED bulb, fits under stock dust cap and internal shroud
LASFIT "L1 Plus" H4 LED: 2000LM, 6000K, 20W lo/20W hi, fanless
Amazon - B0CQL2GRZG
(halogen H4: 1000~1500LM, ~3200K, 55w lo/60W hi)
Beam pattern pretty good. Lights up the road nicely.
Piece of paper will not pull out with used rubber seal
Gap without rubber: Phillips 2.0 mm, LASFIT 2.5 mm
New rubber 4.0 mm thick, used (below) slightly thinner (ID 73 mm, OD 86 mm)
Phillips, OSRAM
OSRAM, LASFIT

Something to figure out: With both LED bulbs installed, turning on the fog lights makes the headlights switch to high beam. One halogen and one LED, normal operation.
I am guessing this might be a 'feature' of the LED programming for daytime running lights on newer cars?
Fog light relay must be wired through the high beams to turn off the fogs with high beam?

more info here: Headlight / Foglight interaction prob with LED bulbs
I would love Alan or someone to bread down exactly the current flow issue that is causing the interaction issues. I was brave enough to experiment with relays until I figured it out but not smart enough to understand why

I put a 30->87 jumper in place of the fog light relay to make DRLs. This makes them light up in the "on" key position, but they are off in the "accessory" position or when cranking.
More LASFIT stuff: H3, 6000K, 2000LM, 20W, fanless - B0C7G4KLXG
Because of the added thickness of the LED base, I had to use a screwdriver, on a bench, to help push the retainers down and over into place.

Great work, Ken! I should note that on later cars, with 2 relay sockets for Fogs on 91+ models, you will need a jumper in both sockets. There is an OEM relay bridge (PN 92861512500) that can be used if you prefer the OEM look.
Also that is a great find for the H3. The 2000 Lumen LED will be about 40% brighter than the 55watt halogen bulb (watts to lumen converter) in there and now all the colors on the front will match. Also, I like the single-wire plug vs the two wire units I have been using.
