Probably already posted one hundred times before, but nevertheless some very interesting AE86 taillights:

I did see some ordinary led taillights for the AE86 before but these tail lights from Wataruworks are just insane! :D

In case you really want them, you can buy them from Wataruworks at Auctions Yahoo. (And use a company like Rinkya to get them handled and shipped!)
Lucky enough Wataruworks also sell normal looking led lights... ;)
