Yes, the bulbs are not HID Xenons at all. To do that you will need a completely different designed light bulb and also need to have either one or two ballasts and a whole lot of associated wiring. I can tell you though that HIDS on the Jetmax work very very well. One of the issues with the standard Halogen bulb on the Jetmax is a 35/35W which is much less than the common 55/60W used in most vehicles. You will likely notice a reasonable increase in light just from swapping out the low rated 35/35W bulbs. And I see that the little retaining clip that I commented about in my Jetmax review has not been redesigned.
Just keep in mind that you might have to be mindful of the wiring used for the headlights etc and whether or not they are designed to take the increased draw that the higher rated bulbs will incur. I found that out by swapping the stock standard 35/35W Halogens for some beefier 90/100W ones. The draw was too much and the wiring proceeded to melt as did the plastic 3 pronged connectors to the bulbs. Replacing the wiring harness means having to buy the headlight assembly which in turn means buying the fairing (tupperware) that houses said headlight too. No matter as it's not expensive here in China. The headlight wiring harness is not sold separately.

Not sure why you are having issues with your lights filling with water. None of that has happened with any Jetmax's elsewhere that I'm aware of.

BTW, your goods will likely be with you soon Mr WirralGhostHunter :)
