Hi all
Can brighter LED bulbs be replaced in the interior light and how does the holder come out to replace them

Thanks

 

If you're talking about replacing the existing LED lights that are already there, then there's some things holding you back.

The LEDs in that car will be either Pulse Width Modulated (PWM) or current controlled through a transistor to obtain variable brightness. You can remove the existing LED, verify its Vf (forward/turn-on voltage...PM me if you want to know how) and buy a new LED with the same Vf that will output more Lumens of light....

THE PROBLEM lies in the fact that your brighter LED will have to draw more current and its highly possible that a higher-current load would damage the LED drive circuitry. Since we're not Lexus, we have no idea of knowing what that rating is, except by trying it and maybe/not failing.

 

Thanks for that mate looks like its a bit more involved than i thoght
but thanks anway

 

most LEDs are 3.7v, if you're looking to replace your dome lights, the 07's and up have brighter LED interior lights.

 

the dome lights the ones above in headlining near the Moonroof switches
Thanks for that
I might see if i can locate one

 

NP buddy.... I only know this because my uncle's 07' 450h is much much brighter than in my 06' 430

 

I wanted to create a backlight for that control panel. At night it's so hard to turn on the light when you can't see the buttons.

 

You're not the only one worker, fortunately I have good memory, so I feel around and poke the left or right lump hahaha

 

3.7V is a huge generalization. 2.4 - 3.7V is a more acceptable range, and again, it comes down to the current rating of the drive circuitry that becomes the limiting factor.

 

I thought a simple low profile LED in the back would light up the crack areas at night, but I tried shining my super bright LED inside and those crack areas didn't light up. In complete darkness and none of the light from the flashlight light up the cracks.

One of these days I will open it up and see if some drill holes could help. My Camry '07, the clear light cover is the button and it's huge so very easy to press it in the dark. Our Lexus light buttons are lump size, a bit more difficult to find in the dark. LOL
