Hi everyone - first time poster here. This is a great community - the DIY thread has a lot of great stuff. However, I couldn't find any information on changing out a HID headlight bulb. My wife's daily driver is a 2002 RX300, and recently we noticed one of the headlights were out. The dealership wanted over $400 for one with a Lexus stamp on it, and $220 for a Sylvania branded bulb. My first thought was no way, that's way too expensive for changing a bulb. I have to admit though that I had no idea how expensive the bulbs were until I started doing some poking around online.

Anyway, can someone tell me what the procedure is for replacing the bulb? I'll admit that I have not yet popped the hood to see how easy it is to get to the back of the headlight... it seems like my wife is always on the go so I have not had the opportunity to do this yet. I thought I'd do a little research here before hand and get the necessary tools and parts gathered together so that I can do this quickly when the opportunity presents itself. Are there any precautions I need to take while doing the swap?

I've changed out bulbs before, but never an HID headlight, and never on this vehicle so I just want to be prepared. I'm generally a pretty handy person and have already done lots of maintenance on this vehicle in the past (brake jobs, oil/fluid changes, etc) without issue, so I'm hoping this will be rather easy.

Lastly, can someone confirm what type of bulb I need to purchase and perhaps where the best/cheapest place to purchase is? The ones I've seen have been sold in pairs - am I supposed to change out both sides at the same time?

Thanks in advance!

Get a reputable brand like Sylvania or Philips online. You need 4300k D2R bulbs. Should be like $90 or something. Pop your hood and behind the headlight assembly, turn the bulbs counter-clockwise 90 degrees, and then pull them out carefully. Do the reverse to install the new ones.

I thought it was 5000 something??

Hey, thanks guys for the replies. I was reading through the FAQ in this area of the forum and it states "Low beam headlamp Part number = 9006". Is this not correct? Or maybe it's for non-HID versions?

Lexus114, thanks for the link. That is a good price.

Low beam should be a d2R# (if you have HID`S) Oh and remember,dont touch the bulb with your fingers/hands.

Gotcha, thanks a lot! It's definitely the 4300K one, though?

lexus114

yes,their are other #`s but they have more blue tint etc.That may be cool and all but it`s harder to see if it has too much tint.Did you know it takes something like 50,000 volts to start those bulbs?? Its a gas,not an element.So they supposedly last an average life of 6-10 years.

I thought 2002 RX does not have HID, unless you have done the converstion .

Starting in 2001,they were an option.

Yep, I'm not interested in changing the color temperature at all... especially since I'm only buying one bulb and want to match what's in the other headlight.

Thanks again. I'm going to go ahead and purchase one of these.

I'm not 100% certain about the RX's bulb size, but if 9006 is what's listed for the part number, that is the halogen sizing.

If D2R is the part number on the actual bulb, then D2R is the type of bulb you would want to purchase.

For HID bulbs in general, you will most likely want to purchase TWO bulbs. HID bulbs have a colour shift as the bulb ages, and thus your headlights will have 2 different bulb colours if you install 1 new one. (i.e. one will be nice and bright, the other, probably more yellowish.)

Philips is one of the primary bulb makers, especially for OEM. HID bulbs for OEM are typically 4300k, which are a tad yellowy. You can purchase higher-kelvin-rated bulbs, which emit another colour (example: 5000k for bright white), at the cost of lumens (light output.) It may LOOK brighter, but it's not.

Philips Ultinon bulbs are rated at 6000k, that would also be a good choice.

Take the bulb out and read the figures printed on it.

All HID headlight bulb is replaced by removing the bulbs from the back of headlight assembly.
