I was looking for some replacemtns to my unsightly amber signal bulbs. I found this great site that has light upgrades. I purchased a pair of their Silver Xtreme bulbs. Basically, they replace those unpleasant stock amber bulb with a silver bulb. The bulb appears invisible under the clear lenses, but when you turn the signal on, it shines amber just like the factory bulb did! It's amazing... And they're only like $20 a pair! They also have these amazing lights called Xenin interior. They replace your interior lights. Instead of the "yellowish" tone of factory interior lights, you get a cool white glow. They look awesome, my friend just ordered some for his IS300. I'm getting them for my RX. They even have this really cool Light Map tool on the Store page that helps you determine which lights you need. You have to check it out! Check them out: www.visionbulbs.com Hope you guys enjoy!
