Nope! The 4th gen gauges don't use twist in bulbs. I do however do this as a business! Satisfaction guaranteed
Urghh! Of course they don't! Hahaha. Thanks for the heads up.

info center lcd is neo4 , glove box is 74, note on switching to leds on the switches, you wont be able to press the switches, stick with stock bulbs on it. 4x4 switch and window switch is neo3 but wont light up alot tho.
Which bulbs use the 4.7v and which use the 12v?
I found a source the will build me the Neo3 & Neo4 using an SMD1210 to run off the 4.7v. The trigger voltage would be set at 3.8v.
Regular neo3 work with 4.7v. HP require 12v
I am not ordering from SuperBrightLED or V-LED.
I have a source that will custom build LED bulbs per my specs. Thus I can get the T3 and/or T4.2 base with a SMD1210 LED. So I need to know of the T3 & T4.2 sockets, how much voltage the socket receive? Is it the full 12v or the reduced 4.7v.
Info Center: LDC display: T4 @ 4.7v DC, Reset/Mode button: T3 @ ??v
HVAC: T3 @ ??v
AC 115V: T3 @ ??v
Center Diff Lock switch: T3 @ ??v
DAC: T3 @ ??v
Heated Seats: T3 @ ??v
RSCA off switch: T3 @ ??v
VSC off switch: T3 @ ??v
4WD selector: T3 @ ??v
Oh awesome! I'd love to get in on some of those haha.
All get 4.7v
Hey all - I picked up a pair of NEO3's, one for my rear window up/down button and one for my reset/mode button. I did not get the HP versions, just the regular NEO3's. For the life of me without really jamming these things in there, they just seem a bit too wide. Has anyone noticed this or is this really snug fit the same everyone else has been noticing when installing them?
Get a really thin file and make the hole bigger. I do this for my customers constantly. It's a pain in the ass.
Hmm ok so its normal. So filing down the PCB or the LCD holder itself would be recommended?
well damn, thats not what I wanted to hear. I guess its time to tear the dash apart and take voltage measurements.
If you got the 12V Neo4 for the lights behind the HVAC LCD, the regular ones seem to light up, but very dim, and the HP ones don't light up at all.
This is because they are built for 12V and those two bulbs only receive 6-7V from the T4R. Why Toyota did this I don't know.
The way to fix this is to dismantle the bulb and change the resistor.
The bulb is glued in so I found the best way to get it out was by taking some pliers and carefully squeezing around the Neo plastic holder just below the LED. This should break the glue.
Finally got around to doing this...
I found that a 50ohm resistor worked best with the blue lights I had for the HVAC LCD.
Tried out 180, 150 and 100ohm resistors first but they all seemed just a bit too dim so settled on 50ohm. May be different though for different colour lights and how bright you want them.
