Common questions
- What is the best weapon light for the SIG M400 Tread?
- Every light listed below is verified to mount on the SIG M400 Tread, and each is graded for how well it suits the gun's job — flood for fast target ID up close versus throw for reaching out. There's no single winner: pick by output, beam, runtime, and price. The ones marked "Ideal" best match the platform's typical use.
- How many weapon lights fit the SIG M400 Tread?
- 17 weapon lights in our catalog mount on the SIG M400 Tread, each shown with its lumens, candela, and the beam profile so you can match output to the job.
- What should I look for in a light for the SIG M400 Tread?
- Two numbers decide it: lumens (flood — how much light fills a room) and candela (throw — how far the beam reaches). Close-range and indoor use wants flood without excessive candela that glares off walls; longer shots want more throw. Each light below is graded against the SIG M400 Tread's typical range.
