    has anyone put an HID kit into their bikes? I just did and used a proper relay which has a direct battery connection, but I still get a very short on/off flicker when I do anything after a couple of minutes, like flip on the high beams, use a turn signal, etc. Do I need to get one of those anti-flicker capacitors now?

    I just went through all the headache of redoing the wiring on the HID relay harness I got because all of the wire lengths were wrong.

    I can only guess that there is a slight dip in voltage in the existing headlight wires whenever I do anything else with other lights (except my brakes). It appears that my high/low/turn signal bulbs all share a common ground wire (yikes Suzuki)

    Is this a new bulb/ballast setup? Brand?

    Factory stuff was halogen. This is Morimoto relay harness + acme speedy start ballast (some kinda TRS brand) and a bulb I got from Diode Dynamics (I ordered from DD because they seemed to have halfway decent quality 3000k h7 bulbs)

    Do you have spares you can swap in to see if it is component related?

    I could try swapping the ballast, but considering the power cut happens when I do random things on the bike, I'm thinking there is some odd shit going on with the bike itself. I emailed TRS to see if they had any ideas, but I haven't heard back from them yet. I just emailed them this evening.

    I swapped the ballast and also directly connected the ballast to the headlight plug, and the same behavior was still happening. So it's definitely something with the bike. TRS is suggesting a canbus system that plugs into the factory headlight plug, but I don't trust the factory headlight plug at all (keeps melting even using regular H7 bulbs) and I'd rather use a relay. Also my bike is an 06 so I don't think it uses anything fancy that would need a canbus system. I'm going to try the capacitor and wire it into the relay signal + wire just to see if that fixes it.

    capacitor didn't work.. I may try to add a delay on/off timer to the relay to it and see if that masks the problem. The current relay has a 5 second delay on, which works fine, but I need a delay off too apparently.

    I ended up fixing it with one of these:
    http://timers.shop/6V-28V-10-Amp-Timer-Wi-Fi-configurable-via-phone_p_44.html

    I wired the relay directly to the battery, the trigger was the headlight wire going in and going out to the relay trigger wire. So when there is a momentary drop in voltage on the headlight wire, the time delay relay will stay on unless there is no voltage coming from the headlight wire for more than a second. This tricks the relay signal wire into staying "on" whenever I switch on my high beams or whatever. My LED corner lights still blink since they are not used in this circuit but I don't care about those, even though they are supposedly canbus, being configured this way doesn't seem to make a bit of a difference.

    I also added a 5 second delay before the HID's turn on as well, so that on top of the standard 5 second time delay on the Morimoto relay gives me 10 seconds to diddle around before I actually have to start my bike.

    or not. light still blinks after the fan kicks on if I'm not revving it. seems like a weird voltage drop. Maybe my battery is on its way out

    No such issues with LED I just installed (GTR Ultra 2). At least it's not noticeable. My guess is the LED has less power draw and it can also run at a lower voltage so any voltage drops don't affect the LED.
