only prob about cheap kits is that they may burn ur lens on the head light, is urs oki?
mine are fine mate, never had a problem and i have been running them for 2 years...
also i wired my dipped beams up not using the stock wiring loom.
i used the headlight switch wired to a relay, then the relay connections are wired to the battery and to the lights.
i upgraded the cables so it can easly handle the power without any risk to the loom,
never hand a problem
