On the XV50 Camry the low beam itself is a tool-free quarter-turn H11 bulb, but Toyota gave you no room to reach it. The driver's side is blocked by the battery and intake snorkel, and the passenger's side by the washer filler neck and coolant bottle. Most owners either pull back the inner fender liner and work from the wheel well, or take the three 10 mm bolts out and lift the whole headlight forward - the latter takes 10 extra minutes and turns a knuckle-shredding job into an easy one.
The thing people get wrong is the bulb type on later cars. 2015-2017 XLE and XSE models often left the factory with sealed LED projector low beams that have no bulb to change, so check for a round rubber dust cap on the back of the housing before you buy anything. The second mistake is not fully reseating that dust cap, which is why so many XV50 headlights end up fogged and hazy inside.

| Nitrile gloves Keeps skin oil off the new halogen capsule, which causes early failure. | Safety | shop |
| Flashlight or headlamp LED, hands-free preferred The bulb socket is buried behind the battery or washer neck with almost no light. | Required | shop |
| Socket set 10 mm 6-point socket, 3/8 in drive Battery terminal/hold-down on the driver's side and the three headlight mounting bolts if you remove the housing. | Required | shop |
| Ratchet 3/8 in drive, plus 3 in and 6 in extensions Reaches the headlight bolts and battery clamp in the tight engine bay corner. | Required | shop |
| Phillips screwdriver #2, stubby and standard length Removes the fender liner screws and the front bumper edge screws if you go in from below. | Required | shop |
| Trim clip removal tool Plastic fastener/panel popper Pops the plastic push-pin clips holding the inner fender liner and bumper edge without breaking them. | Required | shop |
| 10 mm wrench Combination or ratcheting Handy for the battery negative terminal when a socket won't clear the cover. | Recommended | shop |
| Needle-nose pliers Long reach Helps release the bulb connector lock tab and guide the dust cap back on blind. | Recommended | shop |
| Small mirror or phone camera Inspection mirror on a handle Lets you see the socket alignment tabs you are working by feel. | Recommended | shop |
| Low-beam bulb H11 (55 W halogen); 2015-2017 LED trims have no bulb The actual replacement low-beam capsule; replace both sides for even output. | Parts | shop |
| High-beam bulb 9005/HB3 Optional same-visit replacement while the housing is accessible. | Parts | shop |
| Isopropyl alcohol wipes 70% or higher Wipes any fingerprints off the new glass capsule before install. | Consumables | shop |
| Dielectric grease Silicone, small tube A dab on the bulb connector terminals prevents corrosion and heat-related sticking. | Consumables | shop |

Bulb sizes and fastener sizes are identical across the 2.5 2AR-FE, 3.5 2GR-FE and the hybrid - H11 low, 9005 high, 10 mm bolts. The only real difference is access: 2AR-FE and hybrid cars have a bulkier airbox/intake on the driver's side, while the 2GR-FE V6 crowds the passenger side more, so which side is worse depends on your engine. Trim matters more than engine: 2015-2017 XLE/XSE with factory LED low beams have no serviceable low-beam bulb.
| Battery negative terminal nut | about 45 in-lb (5 Nm) - snug, do not overtighten the lead clamp |
| Headlight assembly mounting bolts (10 mm) | verify in the service manual (snug only, they thread into plastic/sheet metal) |
| Fender liner screws | hand tight only |
H11 low beam and 9005 high beam are correct for all halogen XV50 Camrys including the hybrid, and the fasteners you touch are 10 mm plus #2 Phillips; double-check your trim for factory LED low beams (2015-2017 XLE/XSE) before buying bulbs, and confirm headlight bolt torque in the FSM if you remove the housing.
Halogen-equipped XV50 Camrys use an H11 55 W bulb for the low beam and a 9005 (HB3) for the high beam. 2015-2017 XLE and XSE models with factory LED projectors have no replaceable low-beam bulb.
Not strictly, but on the driver's side most people disconnect the battery negative with a 10 mm socket and shift the intake snorkel out of the way. If your hands don't fit, removing the three 10 mm headlight bolts and the bumper-edge clips gets the housing out in about 10 minutes.
Yes, and it is often the quickest route on the passenger side. Turn the wheel inward, remove the Phillips screws and push-pin clips along the top of the inner fender liner, peel it back, and you can reach the dust cap from underneath.
You can physically fit them, but the halogen projector isn't designed for an LED emitter, so beam pattern and cutoff suffer and oncoming glare is common. Some LEDs also need a decoder to avoid flicker or a bulb-out message, and they are not DOT compliant for on-road use.
