Yes, it could be a failing bulb. You could try switching the bulbs from side-to-side to see if you can move the problem to the driver side.

According to Sylvania bulb guide ( http://www.sylvania.com/en-us/applications/automotive-lighting-systems/Pages/lrgmain.aspx ), halogen was standard and HID optional. Toyota used to stamp the bulb type on the lenses of its vehicles but apparently they stopped doing that since the same lenses can be used with both halogen projectors and HID projectors.

Hopefully, your IS250 didn't come with halogen and a previous owner installed an HID kit. It's bad enough that HID kits are illegal and usually blind other drivers but many people who install them don't use a relay to power them from the car battery which can cause them to be unreliable.

Just got a 2012 IS250 F Sport and have the same HID issue. Passenger side turns on fine but goes out after a few minutes. Turning off and on again will make it work but only for a few minutes. Swapped bulbs and same issue, replaced ballast and same issue. Even replaced both 15a fuses for headlights and same issue persists. HID was a factory option and came from factory. PLEASE HELP...

**Update**

So a friend figured out the problem and fixed it. Hopefully this will help someone somewhere.

After replacing bulb, ballast and fuses there were little options left. A friend offered to take a look and carefully observed all connections. Upon inspection, he found that right where the bulb meets the plug there was a little black mark and tiny piece of melted plastic. This led him to believe that there was a bad connection causing heat. It turns out the bulb had a dent where the metal connector is supposed to go and was causing a bad connection. This dent is a design flaw from aftermarket bulbs. Replacing with Sylvania high quality bulbs resolved the issue and both headlights are working fine for a few days now.
