In my list I have electronic flashers. You have to add a ground wire to them, but they are adjustable rate.

I did not know this. I guess those brand new flashers I bought were a waste.

@SteveJ do you recommend a particular one? Are they different for hazard and turn signal, or can you get two of the same kind?

Ah - thanks, Steve. I di don't look down beyond the bulb listing. So, adjustable is required, or do the non-adjustable in the listings also work?

I found the ones in the list work well. I haven't experience issues with them. (I have experienced issues with the ungrounded, 2-pin electronic flashers.) Just get two.

Adjustable isn't required. I just like it because I want to be able to set how fast they blink. 

And here's another link the post with the list: https://www.classiczcars.com/forums/topic/68561-parkingtail-lights-fuse-holder-heating-up/?page=2

One last question Steve - I'm assuming that the (-) terminal on the relay is the one that requires external ground. Can you verify?

[SteveJ]

Yes it is. I put a 6.2mm female open barrel spade (with insulator) on one end of a short piece of wire, and an M6 open barrel ring on the other. I just connected the spade to the negative terminal and ground the ring on a screw.

When I did all LED in 2017 on the external bulbs I user this 2 pin flasher from Amazon and it works just fine, but it isn't adjustable.

I read this recently. I had no idea Daniel Stern was such an expert...

Daniel Stern has frequently downplayed LED lights for automotive applications. This includes replacing incandescent bulbs with LED bulbs in side markers, taillights, etc. While I'm not a "recognized expert" like him, my eyes don't necessarily agree with his opinions.

Is he the Ralph Nader of LED lights?

No, he is knowledgeable about wiring and headlights, but that doesn't mean he's always correct in his assessments.

[HusseinHolland]

I dunno. The light distribution of the Auxito 6500K in the H4 housings is significantly better than the Halogen sealed beams I replaced. Maybe it's different with non-H4 housings, but these have a good cut off pattern that is easy to discern against a wall at the appropriate measurement depth.

The other aspect is the article is I think 3 years old. A lot can change in 3 years
