There is a hard truth with the 10th-gen Accord: you cannot change a low-beam bulb, because there isn't one. Every trim from LX to Touring got LED low beams built permanently into the headlight housing along with their driver module. When a low beam dies, flickers or goes dim on one side, the repair is a new headlight assembly, and that means loosening the front bumper corner and fender liner to get at three 10 mm bolts. LX, Sport and EX do have a conventional HB3/9005 halogen high beam that can be swapped from the back of the housing, and that is the only real bulb job on the front of this car.
The mistake people make is ordering a '9005 low beam' or an LED conversion kit after a quick search, then discovering there's no socket to put it in. The second mistake is trying to yank the bumper corner without removing the wheel-arch screws and the hidden side clips — that's how the fender seam tab snaps. Take the wheel off, drop the liner, and the whole corner comes free in a few minutes. Also verify voltage at the connector first; a blown fuse or a chafed harness is far cheaper than a headlight.

Fastener sizes are identical across the 1.5T, 2.0T and Hybrid — 10 mm bumper and headlight bolts, 8 mm splash shield bolts, #2 Phillips plastic screws. The difference is by trim, not engine: LX, Sport and EX use an LED low beam with a replaceable HB3/9005 halogen high beam, while EX-L and Touring use a full-LED housing with no serviceable bulbs at all. Touring assemblies also add adaptive/cornering wiring, so left and right units are not interchangeable between trims.

The LED low-beam design, HB3/9005 high beam on non-full-LED trims and the 10 mm / 8 mm / Phillips fastener mix are accurate for this generation; the exact number and location of bumper fasteners varies slightly by model year and the headlight bolt torque should be confirmed in the Honda service information.
None — the low beam is a sealed LED module inside the headlight assembly on every trim of the 10th generation. If the low beam fails, the whole headlight assembly is replaced; there is no bulb you can buy.
On LX, Sport and EX, yes in most cases. The HB3/9005 high-beam bulb sits on the back of the housing and can usually be reached from the engine bay, though on the driver's side you may need to move the washer bottle or air intake duct, and it's a tight reach with large hands.
Genuine Honda units typically run from a few hundred dollars for an LX/Sport/EX housing to well over a thousand for a full-LED Touring unit. Reputable aftermarket LED housings cost less but check the connector and DRL function match your trim before buying.
No. The headlight assembly is plug-and-play with no registration or coding required. You only need to check aim against a wall afterwards and adjust the vertical adjuster if the beam cutoff sits high or low compared with the other side.
