Does anyone know if power to the unused (on U.S. models) running light is interrupted when the starter is engaged?

I ordered one of eBay HID kits with the slim ballasts (ended up getting it from these guys because they ship from NJ, not China). It is supposedly a digital ballast. There's been some discussion that the new digital ballasts aren't susceptible to damage from sudden power cycles like the older analog ballasts...meaning it would be okay to have the HID relay powered by the stock H7 socket, but I don't know enough about the technology to know if that's accurate.

If the power to the running light does in fact get interrupted by the starter (as does the stock H7 socket), I guess I'll either have to (1) follow the KISS theory and remember to have the high been selected whenever I start the bike, or (2) use a delayed relay such as the DEI-528T to prevent the light from being powered until after the starter has been disengaged. I don't know of any other power source under the screen that is uninterrupted. I suppose the accessory socket is, but the socket on the '08's is wired through the kill switch...not that that really matters in this case.

I also ordered a set of 55w Piaa 510's in "driving" pattern that I'll fire through an Autoswitch. Just curious if most of you who are using the 510's have the driving or fog pattern?

Power to the euro light is not interupted like the normal lights when you press the starter.

Also, the 510's pwn, i had a pair of driving on my Uly, and they are great, they look awesome with the grill on it too : )

Been giving this some thought...if the Euro light lead is uninterrupted by the starter cycle, it seems the simplest and most logical solution to wiring the HID (to prevent unnecessary ballast cycles) is to do the "always on" mod and trigger the HID relay through the stock H7 socket.

This seems too simple of a solution. Anyone see anything I'm overlooking?

I think *every* circuit is interrupted by the starter, or at least drawn down enough that you wouldn't want to use it. I could be wrong though...it happens a lot : )

That's what I was hoping to determine ahead of time. If the Euro light is interrupted or drawn to the point that it will cause the the ballast to cycle, then I will go the delayed relay route.

Guess I'll have to wait till I can ride up to my fathers place (I don't have a garage of my own) and figure it out for myself with the Fluke.

My lobeam is wired onto the euro line so i have the both lights on mod. When i press the starter, it goes dim but not totally out because of amount of juice needed to get the engine to turn over.

Thanks Froggy. So then I guess the question (that's not easily answered) is how much a of a voltage drop is enough to cause the new HID digital ballast to cycle?
