Sorry if this has been covered and I didn't find it in my searches (a lot of the threads from search results are kinda old), but I'm looking into replacing the 1156 type bulbs on my '89 for both turn signals and back-up lights, and wondering if the automotive LED replacement bulbs these days would require some kind of "load equalizer/resistor" or similar to work on the MK3 Supras, or should most current gen LED bulbs be plug and play? Looking at Sylvania, Philips, and superbrightleds.com brands for starters.

I'm also a little concerned about how hot some of the LED bulbs might run, and I don't want something that's gonna melt or burn out hard-to-replace MK3 hardware. :)

My thread on this is still reasonably current. I did modify the lamp failure box to work properly with the LEDs.

Thanks. Yeah, I did review that thread, but still wanted to renew interest in the topic and hopefully drum up a few more experiences, especially to see if modifications for compatibility are still required with the latest bulbs.

Where does that plug into exactly? : )

Just be aware this may not fit properly.
For mine I would have had to create an adapter so I opted for the inline resistor.
Is there something different about your Supra because of the model year or something else?

Its the flasher relay in the drivers side footwell junction box. Not the easiest thing to pry out while upside down with your head under the dash. .

Thanks. And looks like it’s backwards compatible with incandescent bulbs in case you want to switch back.

Yeah, it basically deletes the rapid-flash lightbulb failure indicator. Funny thing is my car is 30 years old and all the turn signal bulbs are original. Its really pretty amazing.

Some models you would have to make a connector to make it fit. Could be a pre/post 89 thing.
I don't have the photos anymore or I would show you what I meant.

Yep, that's exactly the problem I'm running into. I've assembled some parts to make an adapter but I need to finish it.
