I bought this with extra 5mm and 3mm white LED for high beam Front light and reverse light. The System works well ,English manual included. I put it on my DF03-RA EVO X it makes the car more realistic. Race in Rally circuit and it still works well!!! (Just dirt ,dust and some sand not water). It 's cheap compare with Tamiya but the quality is almost equal !!! (And Actually this one is more functional than Tamiya because it has turning lights!!!)
If you are looking for standard LED System. Get this now. Worth the price ,No Regret!!!
