What an ordeal. Took me about half an hour.

I see 3 possible problems with the ones you're proposing.
1) I'm pretty sure the base on the H21W in the front turn signals is a BAY9s, (not BA9s, which is straight across like on the angel eyes).
Looks like those are BAX9s. They have a different angle on the pins.

2) The H21W has 600 lumens. That's a lot of punch. You may find these to be too dim. This is the closest thing I've found, 300-400 lumens, but I don't know if the heads will fit into the fixture, and there's little doubt they'll cause an error.

3) The front turn signals are also run at low power as marker lights. Results will be unpredictable with LEDs. I wouldn't call this a major concern. I don't know how they're dimmed. If they're run at partial voltage, the LED might not light at all. If they're pulsed, it may work just fine.

Excellent. Thanks for the info as always.

I started looking at aliexpress. Found these:

Claims 700 lumens with few LEDs and only 25w. That seem ridiculous to you?
