On the 9th-gen Accord the low-beam bulb itself is a 10-second twist-and-pull job; the whole battle is getting your hand to it. Honda packed the engine bay tight, so the driver-side socket sits behind the battery and fuse box and the passenger-side socket sits behind the intake duct. Rather than skinning your knuckles reaching blind, most people pull the plastic radiator cover and the 10 mm headlight bolts and slide the housing forward a couple of inches, or loosen the intake duct on the passenger side. Either way it is a hand-tool job with no alignment work afterward as long as you don't disturb the aiming screws.
The thing people get wrong is assuming every 2013-2017 Accord takes a bulb. Halogen cars use an H11 low beam and a 9005 high beam, but EX-L, Touring and most 2016-2017 upper trims came with sealed LED low-beam projectors that have no serviceable bulb - if one of those is out, you are looking at a module or full assembly. The second mistake is handling the new halogen with bare fingers, or not reseating the rubber dust cap all the way, which lets moisture into the housing and fogs the lens.

Nothing changes between the 2.4 L K24W and the 3.5 L J35Y - the bulb and all fastener sizes are identical. The real split is by trim and lighting package: halogen cars use H11 low / 9005 high, while LED-equipped EX-L, Touring and most 2016-2017 upper trims have no replaceable low-beam bulb. V6 cars are slightly tighter around the passenger-side intake duct, so loosening the 8 mm clamp helps more there.
| Headlight housing mounting bolts (10 mm) | verify in the service manual (small 6 mm bolts into plastic/sheet metal - snug only, roughly 7 ft-lb) |
| Battery hold-down bracket nut | verify in the service manual |
| Intake duct clamp | snug only, verify in the service manual |
H11 low beam and 9005 high beam are correct for halogen-equipped 2013-2017 Accords and all fasteners involved are 10 mm (plus an 8 mm duct clamp); confirm your trim is halogen and not factory LED before buying bulbs, and verify housing bolt torque in the service manual.
Halogen-equipped Accords of this generation use an H11 55 W low beam; the high beam is a separate 9005 (HB3) 60 W bulb. EX-L, Touring and most 2016-2017 upper trims have sealed LED low-beam projectors with no replaceable bulb.
No. The bulb comes out through the back of the housing. Most people just pop the plastic radiator cover and remove the 10 mm headlight bolts to slide the housing forward a couple of inches for hand room, or reach in through the inner fender liner.
The battery and under-hood fuse box sit directly behind the driver-side headlight, leaving almost no room for your hand and the connector release tab. Sliding the housing forward or going in from the wheel well is far quicker than working blind.
Usually the glass was touched with bare fingers, or the rubber dust cap wasn't seated so moisture got in. Cheap high-wattage or 'super white' bulbs also run hotter and die early; a quality standard-wattage H11 from a name brand lasts far longer.
