check d casing for cracks... and d glass as well.. re-seal the gap .. joint of the glass and casing wit windscreen glue.. d black type... then try n see if it works... don change the bulbs first.. else if water still seeps in, it might damage d bulb again.. also, the entrance of the wire into the casing.. there should be a rubber enclosure.. see if dat's worn out.. if yes, apply abit of the glue there as well.. but as and when the bulb needs replacement, it could get abit messy..
if u want the brightest spotlights, get a set of H3 hids from HIDSELLER ;)
