The base of the DDM HID bulbs do not have a base similar to that of the stock bulb bases so that the dust/water covers fit tightly.
I taped up the gap between the bulb wires and the dust/water cover with electrical tape but it seems to only be a short term solution to prevent water from entering the headlight housing.
If you have the DDM HIDs, how did you seal the gap between the dust/water cover and the bulb wires? I'm thinking about using some silicone.... Thanks in advance.
