Hi all,

After being hunkered down during the Coronavirus ordeal, I've finally updated all of the bulbs in my GX to LED. I had to do a lot of research, multiple thread and google searches, however here are my results. I figured it would be helpful for everyone who wants to do the same to theirs. Complete bulb list and photos at the bottom. The only bulbs I did NOT replace are the Amber LED Mood Lights in the front housing / Amber lights in the front foot wells / Amber lights behind the door handles. For the Interior, I chose 3000K Warm White, as the brighter 6000K are too bright for my eyes in the interior at night.

The process was surprisingly easy to be honest, with the most time-consuming part being the disabling of the DRL to run LED Turn Signals with built in resistors (I didn't want to mess with adding resistors, and the bulbs I purchased work flawlessly - both front and rear). I am by no means mechanically inclined, but I only struggled removing the DRL wire from the pin-connector. Everything else was pretty much straight forward and easy.

Total cost for ALL bulbs was < $250.

To run LED turn signals, you have to disable the DRL as the bulbs I used have built in resistors. Thread here:

To change your Turn Signals / Side Markers / Parking Lights, everything was done from under the hood. Thread/YouTube here:

(ignore the resistor portion halfway through)

To change your Reverse Lights / License Plate Lights, YouTube link here:

To change your Fog Lights, YouTube link here:

To change the Interior Lights, YouTube link here:

For everything else, it was pretty much straight forward without having to search too much, so I've left those off.

Thanks for the detailed write up on this! Do you have recommendations w/ links to the LED Bulbs used? Thanks!

Dunno what they used but I almost exclusively use Alla. Have for years, good quality and very bright. Plus very good customer service. If you use the amazon app you can search by bulb type directly on their store which makes it easier.


Example of my interior.

Good morning, thank you for all this information. I've changed pretty much most of the bulbs on my 2004 GX470. But when I was changing the map lights, first it blew the fuse. I changed it & everything still works as it should, but the bulb I replaced does not come on when you open the doors. And when you click it to turn it on I have to click it like 5 times. Maybe someone here can help with why it's doing this. Thank you all.

weird. Haven’t had any issues with what I installed. Been 6 months and a whole lotta miles later (12k lol).

rikko72

Yeah it's weird. I've changed everything but the reverse & the fog lights. Want to wait until after Xmas (maybe I'm getting them as a present, lol). So just the driver side bulb of the map lights is doing this. I am baffled. Oh well, maybe I'll figure it out at some point & will let you all know.

Do any of these bulbs need to be amber? Before I found this thread I replaced my blinker / DRL bulb and I was told to get amber. Im going to replace everything with LED now and I know that the DRL gets disabled, but I assume the blinkers would blink white without amber lenses, correct?

nycbenz

Yeah, the front turn signals will blink whatever color the lights are, so I would get Amber.

I just bought an LED bulb kit for $20 and replaced all the interior lights - not the best or brightest but they work. I'm curious, did you purchase name brand LEDs for the interior? I'm not in love with the 6000K color and wish I would have hand picked the lights. Could you share what LEDs you used for the MAP lights?

nycbenz

These for the front dome/map lights:

These for the 2nd and 3rd row:

Make sure you get the soft/warm 3,000k vs the bright white 6,000k.

Ive had no problems in the almost year they’ve been in the car, plus they come with a bunch of extras in case a bulb goes out for whatever reason.

Thank you sir!

I am happy with my LED low beam (Sylvania) and LED high beam (don't recall brand) but I am on my third pair of H3 LED fog lights off ebay and they have all been terrible (original halogens were better) on my '08 GX470.
Has anyone have a brand of LED fog lights that work well?

nycbenz

here’s what I went with. No issues at all in over a year driving - my lights are 100% on all of the time, and I’ve driven roughly 20,000 miles since I’ve installed them. They make other colors instead of yellow, but the brackets were not lined up correctly so the beam isn’t massively bright, but I’m ok with that as I hate super bright yellow fogs (in the comments a man used a dremmel to line up the brackets correctly):

LeX2K

H3 is a small form factor so LEDs in this size have a high failure rate. Unless you have room for a version with a fan it's better to go HID.
I tried these exact ones not bright enough for me not even close.

Thanks nycbenz.
