How to Replace LED Headlight Assemblies on a 2018 Honda Odyssey (Both Sides)
Step-by-step bumper removal, tools/parts list, and headlight bolt torque specs for a clean install
š§ Odyssey - Headlight āBulbā Replacement
On your Odyssey Elite, the main headlights are LED units, so there usually are no replaceable headlight bulbs. If the low beam/high beam is out, the repair is typically replacing the entire headlight assembly (left, right, or both).
Quick check (so I guide you correctly): Are you trying to fix the main low/high beam, or a front turn signal/parking bulb near the headlight? (Those are different parts.)
Difficulty Level: Intermediate | Estimated Time: 2.0-4.0 hours
ā ļø Safety & Precautions
- ā ļø Let the front end cool down before working near the radiator/fans.
- ā ļø Turn ignition OFF and keep the key fob away from the van.
- ā ļø Disconnect the negative battery cable if youāll unplug multiple front bumper connectors.
- ā ļø Your Odyssey has front sensors/camera equipmentāpull the bumper cover gently and do not yank wiring.
- ā ļø Support the bumper cover so it doesnāt scratch paint or tear tabs.
