Well this is encouraging, thanks I'll give it a go then. I assumed since they wanted so much it was because they were going to replace that control panel or something.
Do you happen to have those bulb numbers handy? Are they something I can get at a parts store or is it a Toyota only type bulb?
I don't recall the specific bulb numbers. You can probably look in the manual or have the service guy pull up the pic with bulbs at the dealership.
I think each bulb is like $4. Just make sure they give you the right kind for there are a few different ones.
Below is a link you can use to help with the basics. There are others that are more detailed if you want to search further.
