Updated LED Interior Lighting Thread for 99+

If you mean the ring around the cigarette lighter, that is actually a built-in bulb and needs to be ordered from the dealership. The other option, which I'm taking, is simply buying a bulb holder for a 74 base and doing a little engineering to replace that factory bulb socket with an aftermarket one so I don't have to deal with the limitations of having an incandescent.

My Cluster backlights are VLED's. I tried the SuperBrights for fun and they definitely have hot spots. The output and angle of dispersion on the VLED's are simply better. If I could only afford VLEDs in one spot, it would be the cluster backlights.

The part number for the bulb that goes around the cigarette lighter is 84999-10250. When I bought it from the dealer I think it was around $7. I actually have the old one disassembled, and I'm looking at how it might be possible to convert it to an LED. I think the hardest part about adapting it is going to be getting the LED to sit at an appropriate depth to illuminate the ring properly.
 
Rear defrost, ECT, and rear window share 2 bulbs. Both are Neo Wedge T3's. I think the rear window switch has it's own and then rear defrost and ECT share the other one, but it might be the rear defrost by itself with the ECT and rear window sharing the other.

The only things in the center that wouldn't be a Neo Wedge T3 as far as I know are the ash tray light (I believe this is a 74, but it's been a long time since I did this), the light around the cigarette lighter (Bulb is built into the connector so needs an OEM replacement part), and if you have the auto climate control the back light for that is two Neo Wedge T4's (The climate controls knobs and buttons are two separate Neo Wedge T3's in addition to the T4's for the back light).

For clarification, here is the entire panel disassembled so that it should be clear which bulbs light up various sections:

It's actually super easy. Just grab a T1.75 wedge base socket with pigtails.

T1-3/4 Wedge Base Socket - Wired | Super Bright LEDs

It literally just slips right into the old spot where the prewired bulb went. I cut the adapter off the stock wiring, spliced the new base socket in, and dropped in an amber led (74).

Thanks. That should be much easier than trying to make something work in the old housing. I had gotten far enough to determine that the old bulb was a T-1 or T-1.75 Wire terminal LED, but options for replacement LED's in that size are limited, and I was only finding stuff that was 1 or 2 lumen output. Being able to put a 74 there should work much better.

Tbh I just ripped it out with some small needlenose pliers and jammed the LED in. Works totally fine, no need to be more complex than that :thumb3: Though I probably would've done this if I saw it at the time
Looks so much better without color

I had originally jammed my ashtray light in there since I took my ashtray out in lieu of an additional switch panel, but it never looked quite right to me. When I was ordering some stuff from Superbright I grabbed a few of those sockets b/c for $1, it's hard not to have them laying around. As it turns out, those sockets just happen to fit with oem precision in that spot.
 
Does anyone have a link for the VLEDs for the 74 cluster bulbs? No hot spots preferably. I have an '00. Thanks!
 
2002 dash cluster swap

Howdy!

I hope I'm not committing a forum faux pas by resurrecting this thread. I just didn't want to start a new one when this thread was the basis for all of my own work. If I need to start a new one, please advise.

Thanks for all the excellent information here. I used it to perform an LED swap for the interior of my 2002 Runner. I used the method for testing polarity as instructed and ensured that my dash light bases were oriented correctly.

After completing the swap I noticed that my blinker dash indicators do not work and my P light in the dash doesn't work as expected. I've double checked the polarity and orientation of the base twice as well as fuse integrity.

This leaves me with a few questions.

1. In the dash cluster are there some lights that have an opposite polarity? Like the Park indicator or the blinker indicator?

2. There are some lights that seldom turn on. Namely:
VSC
Airbag
Check Engine
AT Oil Temp
RR Dif
ABS
Etcetera...

How can we be sure that the leds are working as intended for these lights? IS there a way to force illumination of these signals or should they all light up when the ignition is set to accessory power during pre-start?

Thanks!

Hi all- thanks so much for this (and the other) great threads- I popped a few LEDs in to replace OEM bulbs that went out, and it is looking GREAT!
