This is the ONLY set that has been specifically designed for the smart. No other set on the market was specifically designed for the smart headlight housing.
Check the pics carefully... You always get what you paid for.
We invested a significant amount of funds in to producing a smart car specific HID set. There are no external ballasts, no external wires and no double sided tape! These sets are designed to simply replace the existing rubber cap on the back of the headlight housing.
If you are planning to purchase both the low and the high beam check out our combined listing for additional price breaks.
If you are interested in a simple, good quality, generic version of an HID conversion kit with an external ballast that is mounted with double sided tape we can offer you those as well along with the best warranty and price.
