So I took my M Roadster out for a spin this weekend and no issues with the turn signals. Took it out tonight and right blinker blinks fast. I have seen this before on my other cars and bikes. When bulb is out, or wrong resistance bulb is in, or a relay. Well, it dawn on me that over weekend I did not drive in the dark. So I shut the lights off, blinker goes to normal speed. I turn my parking lights on, it blinks 3x faster. All bulbs are working. I shut the parking lights off and it’s back to normal. This just started happening because I drove this car in the dark before and so not recall blinkers going bonkers. Any ideas?

Bad ground on one of the turn signals, probably in the rear housing.

Best post I've seen in a while!! Too funny
LOL. In my defense, it was roughly 1:30am and I was typing it from my phone and “u” and “i” are right next to each other. That said, it is pretty funny indeed. Now instead of laughing, propose a solution. One that does not involve a jar of lube, or a trip to proctologist.
Is the 3x blink on both sides or just one? If one, have you swapped bulbs side to side to see if the problem followed?

When the parking lights are off, your turn signal is able to ground through the parking light wire. But when the parking lights are on and there is voltage there, that ground path goes away.
Either that or you are low on blinker fluid.

Funny, as I started reading your last reply, I was thinking it’s going to go the other way and was about to say “but there is fluid in the rear view mirror...” LOL
Yes, and on one of my motorcycle forums, newbies always get dinged on getting the slower red model vs. faster blue due to wind resistance to the color shade and etc... some would bite.
If you let all the magic smoke out of your electronics they quit working.

So I let all the magic smoke out, kicked the hamster wheel and wiggled the connector on my front right blinker and it’s back to normal. Disaster avoided. Thank you to very wise members of this board. Wise or wise asses , nevertheless all is good. Thank you!
Cool. Glad to hear you tracked it down. I'd pull the bulb and clean up the contacts and check the wire/connector. Use a little dielectric grease on reassembly and you should be good. These kind of problems have a tendency to come & go.
Had the same issue recently. Swapped the relay and no change, took both the bulbs out to check for corrosion etc and put them back. Been working fine ever since
