I have tried searching for a guide that has all of the interior light bulbs listed, but can only find the dome light bulbs. Has anyone put together a list of all of the bulbs in the interior? 07 rx400h.

^ Helpful video with installation guide and all bulb sizes.

The LEDs with a metallic base are generally higher quality and brighter than the flimsy plastic ones. While you’re doing this, I’d get some super bright reverse lights as well, they help me see out my reverse camera at night. Bulb size: 921.

I need this.

Might upgrade.

He only mentions the first two bulb sizes, does not go into detail in the other sizes

The reverse lights were the first "mod" I did!

Which LED's would be recommended in the Reverse light slot for my 2008 RX350?

I know this is a 330, but taking off the back pieces looks very similar:

MattRX

Here's a quick list I just put together - hope this helps!

Front dome/map light:
1x 31mm festoon bulb
2x BA9S bayonet type bulbs

Sun visors:
4x 29mm vanity bulb

Middle dome light:
1x 31mm festoon bulb

Door/courtesy lights:
2x 168/194/T10 "peanut" bulbs

Trunk light:
1x 28mm festoon OR 31mm festoon bulb (I used 31mm for extra brightness but it was tight)

License plate light:
2x 168/194/T10 "peanut" bulbs
LED drop-in assemblies are also available

Glovebox:
Already LED, you'll have to solder in a better bulb

Footwell lights:
Already LED, you'll have to solder in a better bulb

This is for the 2004-2009 Lexus RX330/350. I'm going to assume the 400h is the same as its roots are that of a 2nd gen RX. If you're not 100% sure, I'd take the bulb out and measure it with a ruler or caliper and see how long it is in mm.

I have these in both my Highlander and RX350 (they both use 921).

These are insanely bright and the build quality is fantastic! All-metal construction, dual-polarity, a little reflector on top, and BRIGHT. These are basically rear headlights for your reverse lights, I'm not sure why anyone would go through the trouble of hooking up external lights without trying these first.

ya i might eventually do this upgrade as well; or just do what my brother did in addition to this and that is he upgraded the standard halogen bulbs on his 2015 accord to led's for the main headlights and the fogs as well so i was considering that as well but i dont think i need them right now because the headlights that came with my rx is the option package that has the xenon hid afs lights and they for the most part are pretty bright(brighter than the standard bulb but not as bright as led's)

I would not go from a D2S HID bulb to an LED in a projector; your overall light output will suffer in the end of the day and you will be disappointed. Sure, maybe the LED itself may be brighter, but the HID’s advantages are how it is focused/aimed down the road in a project housing due to its halogen-like beam pattern & focal point.

I would consider it if I was on a budget and wanted to replace a halogen bulb in a projector, but I’ve yet to see an LED bulb in a projector come close to that of a proper HID. My RX has the original Toshiba 4300k HID bulbs and they not too bright anymore but get the job done. I’d myself would go for some 35w OSRAM 5000k bulbs when they fail. The other problem with LEDs is that you are essentially forced to use 6000k as a colour temp, while HIDs can be 4300k (stock), 5000k, 6000k, etc.

iMSQ

3 years ago I bought this 1550 lumens but one bulb died in 2.5 years
I decided to buy another brand - - but it doesn't work for RX (LEDs are too small and too few) so there is no improvement comparing to standard bulb
So, I returned to previous brand and bought 1600 lumens

iMSQ

Don't remove parts 1 and 3, only part 2. Moreover, if part 1 was removed then it should be installed back BEFORE part 2.

Goose77

I haven't removed anything yet. Just asking to see what others have done. So, both the links (1600 lumen one) to the Amazon LED's above will in fact fit a 2008 RX350, right?

MattRX

Before I put my current bulbs into my car, I used ones similar to what iMSQ used. These bulbs are pretty bright and have a decently wide spread too, however their light intensity and beam pattern aren't as nice as the ones with the little "globe reflector" on top which are the new design. I have tried these current bulbs in my cars ('02 HL, '14 RX) a 2014 Highlander and a 2006 Honda Civic and they always fit very nicely. The reason why these bulbs are so nice fitment-wise is that they physically resemble a regular 921 bulb, so fitment will be on par with any car that uses a 921 bulb already.
