I have a burnt out low-beam headlight on my Hyundai Sonata. In searching online, all I can find is are the full headlight assemblies. I can’t believe that I can’t get (or replace) just the bulb. (Make that plural, of course; I plan to replace both low-beam bulbs while I’m at it.) So I went to the website of a local Hyundai dealership to try to find the exact part. They will give me no information unless I can give them the part number, which I can’t find. I’m willing to pay a little bit extra for an OEM part, or I’m willing to pay a little bit less for a third-party manufacturer from Autozone or somewhere, but I can’t even find what it is I’m trying to buy! Help? ---

Check this chart [http://www.lightbulbs4cars.com/hyundai%20bulb%20guide](http://www.lightbulbs4cars.com/hyundai%20bulb%20guide) Depending on year it’s either an H7 or 9006. After you identify your year, any autopsies store or WalMart etc. Should have the bulb. ---

> [@GaryM](#): > > Check this chart > > [Hyundai replacement bulb guide](http://www.lightbulbs4cars.com/hyundai%20bulb%20guide). And as non-snarky response, yep, that’s it: H11B. Thank you. I must admit to some trepidation that they say the emitted light is different. I’m 58 and my vision is not what it used to be. The original lights have been just fine with my vision. ---

Damned autocorrect! There are some bulbs brighter than the oem that are still legal and won’t cause your wiring to burn up. The Phillips Xtreme series are highly recommended by the folks on candlepowerforums. ---

That’s an H11, and not an H11B. Thanks, but I’m not going to order online. I’m going to buy it at a store, try to install, and if it’s not right, march directly back into the store. My metric wrenches and socket set are already in the car waiting. I do appreciate your help. ---

I can’t believe that I can’t get (or replace) just the bulb. European cars may have some rare bulb types, but well you’d then just go to a a larger , or euro specialist , parts shop. But for asian, and american, its going to be just a standard type, and no one bothers to lists the model their bulb fits too. Just remove the dead one and take it to the parts shop… ---

You didn’t say what year your Sonata is (why doesn’t anyone here ever give enough Information when asking these questions?) but are you sure you don’t have HID headlamps? ---

Don’t think locally. Some dealerships have the full parts catalog online and some just have an order form where you put your part number in. [Here’s](http://hyundaipartsdepartment.com) a site with the full part diagrams, just select the year, model, options, then ‘electrical’ then ‘front lamps’. Note that there may be “W HID” and “W/O HID.” The best is to find a dealership that allows VIN lookup, but unfortunately I don’t see one for Hyundai. ---

No shit. You also need to know that the little force needs to be applied on the inside of the headlight assembly, because the outside has a steel flange that isn’t going anywhere. And, as I told my father, thirty minutes for the first one, thirty seconds for the other. It’s a lot easier once you have a vague idea of what you’re doing. But at any rate, I now have two working low-beams. Hurray for me.
