What relay to change turn indicator bulbs to LED? 1986 R80RT

[tallcanuck]

Changed my turn single bulbs to LED bulbs and got the dreaded hyper flash.

I am an electrical noob and I don’t know the three prong relay with resistance I need so the LED bulbs work and I don’t get hyper flash.

I contacted Euro motorsports and they say they don’t stock one for my year of bike
Can anyone advise me what I need?
Thanks very much.

Snowbum has a page on lamps, bulbs, etc., and near the top he discusses LEDs.

Lamps, bulbs, BMW motorcycles, cars,trucks. Substitutions, technical details.

He suggests contacting KatDash for some help:

However, I don't see relays listed for the post 1980 bikes. Maybe EME is on to something.

Kat's website says that LED turn signals will NOT work on an '81 to '95 model year, even with a different flasher module.

Alternative: you can add an extra resistor in parallel (one per side, NOT one per LED, unless space is an issue and you need the smaller size of a lower-wattage resistor) to pull the extra current needed for the flasher.
So, you do NOT save power, you just get the longer life and instant on-off of the LEDs.

Wow. Ok thank you Paul’s. You just saved me a lot of grief.!!

Yeah, Snowbum mentions the resistor feature in his LED article.

Thank you 20774!!

FWIW I don't think the instant on/off property of LEDs is desirable for signal lights. It's harder to notice the change when it's so fast.

Anton- Concur 100%. I recently fitted LED signal lamps and then almost immediately went back to standards after numerous "constructive" comments from my riding partners.
