Went to VatoZone last night, needed to replace my failed OE flasher, and found that this $28 unit is a direct OE replacement and is LED compatible.
I've installed and it works great with both incandescent/led bulbs. Much cheaper than the NAPA/Advance alternatives for OE replacement (those were $45-50) that I'm unsure if they're LED compatible or not.
Just fyi. Cheers
