No idea... got them as a Bday present from the GF.

Probably something cheap and unreliable. :icon17:

USDM PIAA 6,600K (19994)
Flickered one second on very first turn on. No problems since.
2009 head lamps.

Anyone know of another place besides retrofits to get RIGG bulbs?

Nope. I gave up looking for them.. ur 2010 should work with just about any brand though. The flickering issue is just for 2011 since there is a difference on the ballast

Thats weird, ive been having the same problems, i bought NISSAN 350Z 370Z D2S HID HEADLIGHT BULBS HI+LO BEAM 10K | eBay

And i have to turn them on and off 2-3 times before they fire up! Sucks because i like using the auto light function!

Riggs bulbs
 

Retrofit just contacted me and said:

Thanks for the inquiry.

Unfortunately, we no longer sell RIGGS bulbs. If you're looking for a bulb that works well with the OEM Nissan ballast, the new Morimoto 3Five bulbs do: D2S: Morimoto 3Five (35w) - HID Bulbs from The Retrofit Source Inc

So these Morimoto ones dont work aswell? Looking around for a few easily accessible bulbs that work with the OEM ballast is abit of a challenge, especially here in Australia where everything is overpriced! :mad:

Was on the fence but now its a NO
 

I was looking in to going with an aftermarket bulb as well, however reading all of the problems you guys are having with these... I think I'll save my money and stick with OEM! having a Z with a lazy eye would bother the hell out of me, and the horizon issues would as well.. So OEM for me!

I bought Phillips Ulitinon 6000k, they work perfect and dont have that lazy eye problem, trying to find parkers to match them!

So after reading this entire thread I still am not sure what to go with. I want a bulb that is 5000-6000k. OEM or better in quality and none of that flip the lights on 4 times and flicker stuff. I have a 2010 so it should help I believe. I'd like to spend <$100.

Im using D2C 8000k and ordered it from ebay. it was 20 bucks for me. And nothing wrong with them. It doesnt flick either.

8000K is freaking blue as hell. How do you not get pulled over with that stuff

The one I have is not that blue. Just a tint of blue. I'll post some pic this week.

Can you point your headlights at a wall or a garage and take a pic? I wanna see this color. If it's like 6000k then I'll get it. Even more so if its somewhere between 5-6000k.

I will take some pic this weekend in my garage on the wall and post it up. I think different brand have little different temp color.

This actually not that blue. It look a little bluer on camera than look in person. You wont get pull over by that.
