Hi Im looking to upgrade my dome lights. I know that the model # for the conical shaped dome lights is DE3175 but there another 2 different bulbs for the 2008 model. The problem is I dont know what model # they are.

 

Because this question is not specific to the hybrid vehicle, I've taken the liberty of moving it to the RX330/350 forum where it will get more exposure.

 

Its a DE3022 bulb, which id nothing more than a 8MM FESTOON bulb. They sell surface mount LED panels with 8MM adpator for the FESTOON bulb which is a real bright upgrade. I had those on my last Lexus and they were much whiter and brighter.

 

where do you purcahse these lights? i have different LED's i installed but i'd want as bright as possible

 

I put in something like this one, its much brighter. You will have to measure the housing to make sure it fits, the LED matrix comes in all difference sizes. The adapter is a 9mm bulb, you will have to make it fit into a 8 mm socket, not too differcult.
