Absolute crap product and the seller is an arse hole. You have to sand the top of the bulbs etc. The should have come in a "Plug and Play" kit. The only part of this kit i still use is the blue LED in the ignition ring. STAY AWAY FROM THIS SELLER
If you want proper ones.... there is a guy on Lexus owners club uk who goes by the user name "fargo".... he has made some nice kits, many colour options..... his kits are well regarded, don't know if he still does it but i can ask him if you want?
