if you keep the fog switch in the off position when you turn off/park the car, when you lock/unlock the doors, they wont flash. The only reason they do flash is that they are connected to the parking lights circuit, so when those flash.. the fogs go on/off as well.
try it for yourself, its been a while since i used my SS but im pretty sure thats its deal.
and btw, HIDs do not draw more than a regular bulb. less actually. Thats why HIDs have an ignitor and ballast, to take the regular 12v and convert it to hid requirements which i think is like 25k volts to ignite and 10-15k to sustain the burning gas.... but as for burning out the ignitors, a constant on off could affect them over time.
and..lol... i do believe there is a way to set your keyless entry to NOT flash any of the exterior lights and not sound the horn. instructions for that should be in the owners manual.
