What the AI looks for in Bike Lighting Parts & Accessories

Mount interface
Match the interface exactly: the light maker's own clamp, a GoPro-style two-prong mount, or a Garmin quarter-turn mount on an out-front computer mount Lights that hang under a computer mount only work with the specific adapter made for their body.
Handlebar and seatpost size
Check bar diameter (25.4, 31.8 or 35 mm) and seatpost shape (round, aero or D-shaped) before buying straps or brackets Universal rubber straps slip on oversize or aero shapes.
Brand-specific replacement parts
Buy replacement mounts and straps from the light's manufacturer and the same product line Clamp and rail shapes differ even between models from the same brand.
Dynamo compatibility
Dynamo lights need a matching hub output (6 V / 3 W standard) and correct connectors, and the taillight is usually wired through the headlight Mismatched lights flicker or underperform.
Batteries
Use replacement cells of the exact type and protection the light specifies (for example a specific 18650 format), from a reputable cell maker Wrong or unprotected lithium cells can damage the light or overheat.

Questions

Can I mount my headlight under my bike computer?

Only with an adapter made for your light's body, or if the light already has a GoPro-style or Garmin-style interface. Check the light maker's listed compatible mounts first.
