Default Automatic Headlights - Only One Side Turns On

Sorry if this has already been addressed. I didn't see a similar thread with my specific issue.

I've got a 2006 GS 300 and in automatic mode, when it turns on my low beam head lights, the driver's side does not turn on automatically. I have to manually turn off the lights then turn them back on and everything works fine. I have aftermarket ~5000K bulbs installed, Garax, I think (I assume they're real ones, I bought them from either XenonDepot or Nigel... can't remember). The bulbs are about 3.5 to 4 years old. Ballasts are the originals.

You all think it's the bulbs or the ballast? Thanks.

On a side note, I wasn't really impressed by the Garax. Might switch to Ultinons. Then again the stock 4300k sucked as well. I'd like to get some halfway decent lighting on this car without having to retrofit lenses and *****.

EDIT: The bulbs are not from XenonDepot or Nigel, they are from theretrofitsource.com (D4S: Morimoto XenGreen (XenGrnD4S) Kelvin 5000K). I don't think they are a quality product, IMO.

You guys took too long to answer. I'm impatient, so I bought new bulbs for both of my cars from Xenondepot using their sale promotion for 20% off.

66240CBI D2S - Osram Xenarc 66240 CBI HID Bulbs (for the 997)
66440CBI D4S - Osram Xenarc 66440 CBI HID Bulbs (for the GS 300)

Even if the bulbs weren't the problem with the automatic headlight issue, I still didn't like the output on the 3 year old Morimotos. I'll keep you all posted if the problem is fixed after the install.

i didnt have a good experience with new morimoto bulbs either. Both sides turned off randomly and I ended up getting a refund on them.

The Osram bulbs provided that they're genuine should work much better. I replaced my morimotos with Phillips and they've been perfect since.
