I have a 2007 LS460, and the low beam headlight on one side goes out intermittently. After driving for 20 min or so, it will illuminate again when cycled off then on again. Any thoughts or suggestions?

 

I had same problem. Bulb is going bad. Replace both of your bulbs. If your a DIY person bulbs can be purchased for less than $60 a pair on ebay and 30 min total installation.

 

There are a lot fake Phillips HID's on ebay make sure they are the real deal.

 

Iv'e been wanting to go with 5k....does anyone know if these are any good?? http://www.kbcarstuff.com/D4S-XenonD...b-p/xt-d4s.htm but then again I am a complete noob when it comes to lighting so please don't bash me if these are horrible LOL

There is a clublex discount when you use the coupon code CLGB08 so 2 bulbs for under $100 is cool

 

I had that brand on my IS350 and I never had any problems with it.

 

I went with the 5k's and I didn't really notice too much of a difference from the stock 43's. Maybe a hint more white.

My 4500's I ordered from DDMTuning are way brighter!

 

Good to know. Thanks for the input
I just want a little bit whiter than stock and definitely no blueish AT ALL!! not into the 6k+ stuff myself... the only thing I'm worried about is that the bulb is made for 35w and some say that running that on 50w will cause some serious damage...but I think 35w is stock on our cars right?? (again still a lighting noob )

I'll probably buy these and save them for when mine start to go bad or I have access to the headlight assembly for whatever reason...

 

I bought a pair off a retailer on Amazon just shy of 90 days ago, not sure if I should say the name here. They came in a Philips box and appear to be factory type bulbs (but how do I know). Just a few days ago, one headlight started turning off after a few minutes.

I can see a pattern: Turn on car, both lights turn on and are a nice white/blue factory color, about two minutes later they are more of a yellow color, and after about another 30 seconds the passenger headlight turns off completely...leaving only one yellowish headlight that just stays on.

If I turn the car off and back on, the cycle repeats.

Now I'm stuck with a dilemma. If it's knock off bulbs then I don't want to get a replacement bulb from the same retailer and should ask for a refund. If it's a ballast issue then I can take it to the dealer under warranty. However, if I take it to the dealer and it turns out to be a bulb issue, I'm assuming I'll be saddled with a hefty bill.
