Here is the write up on how to swap out the standard amber looking wedge bulb to a bright 20 lumen LED. This instruction is for my 2004 LS430. Not sure if it's different for other years, so YMMV.
First off, you need to remove the reflective mirror piece. It is held together with a trim surround.


Use a small jewelers screwdriver and pry the clip up. Work your way around half a circle and the rest should just pop off.



Next, the mirror is held in place with gooey black adhesive around the edge and also some white adhesive toward the center. Use a knife to work your way around the edge separating the adhesive.


Note: There is two small electrical connector that makes the dimming of the mirror possible. They are just pressed straight in and it should pop off very easily when you pull the mirror off the backing.

Here is what the back of the mirror looks like.

Unscrew the single center screw.

And pull mount off.

This is what it looks like after the mount has been pulled. Remove the 4 screws on each corner. This will separate the mirror housing.



Now, you are finally able to reach where the light is installed. Pull the housing of the light off and by twisting counter clockwise, it should release from the bulb housing, exposing this:

Make sure it does light up before reassembling, otherwise you have to take it all apart again
It seems like alot of steps but it really isn't. The hardest part is to reattach the two connector back onto the back of the mirror. Trick is, get someone with small fingers to help as they should be able to reach back behind the mirror backing, holding the plugs in place while you line it up and reattach the mirror. All this should take about 10 to 15 minutes max. Good luck.

Ordered it from www.superbrightleds.com They are the WLED-WHP version for $4.95/each. They are the brightest ones to use. The WLED-X5 / X6 are ok but doesn't give enough lumen. I'm guessing these should last a lifetime as they are using what looks like the same cree bulb as used in flashlights and the mirror lights up only 15 seconds or so.Originally Posted by mkivowner
Where did you get LED from? I replaced some LED on '04, but it won't last that long.
I also swapped out my 2 trunk bulbs with these WHP and it is super bright. It will be night and day difference than stock especially if you leave the diffuser plastic off.
PS: Did you swap the amber foot light under the dash with LED? It looked like a complete unit and not a bulb swap.

My bulbs are on the way!
FYI:
The 194 bulbs (wedge) will also work in all the doors, and the lights above the daytime running lights.
Front Pass door

Rear pass door

BA9 bulb's will replace the maps and rear passager lights.


Reverse/back up 194 (wedge)



31mm festoon will handle the dome light.

I did not swap those out b/c i like the amber color, and it is not distracting. Originally Posted by airtime
