Ok, this kinda falls into a couple categories but most of it is exterior so I put it here.
I went to LED Lights & Accessories - SUPER BRIGHT LEDS earlier today. They list the aveo, and tell you each type of bulb you need to purchase. Unfortunately they don't tell you how many so pay attention to the quantity if you use this method.
I went down their list and ordered 2 of just about each type of bulb using mostly the SMD style LED's and the total came to around 350-400 US Dollars. Pretty pricey conversion to do all at once, but can be done cheaper. I want my lights to be bright so I aimed for some of the pricier bulbs. I don't see this going for less then $300 though.
This is for all exterior bulbs and the dome and cargo lights. Does not include headlights (I don't like LED's for trying see where i'm going)
Just some info I thought someone may find interesting. I like the site, it's well laid out and pretty informative, unfortunately I have not ordered from them. yet.
