I haven't had a go at rewiring the bulb holders I mentioned yet. Something kind of related though, I found in
this article on OVT that they had suggested a specific flasher relay suitable for LEDs, and since mine was buggered I figured i'd give it a shot.
The relay was only $15
on eBay and works great, only for standard halogen bulbs so far.
The buggered one (OEM) either did not flash at all, flashed slowly for a short time and stopped all of a sudden, flashed quickly for a longer time and stopped all of a sudden, or stayed on with the switch but did not flash at all.
The new relay has the same terminal labels as the OEM one, and plugs right in. It is about 2/3 the length but the same diameter. If your indicators are giving you strife, then definitely grab one. The flash rate is faster than the slow of the old one and slower than the fast, and the tick noise is about 1/3 of the OEM one.
I'm going to order some indicator, park, brake and reverse LEDs soon based on that guide and give them a go. I'll post the results :)
