Do I need to run new wiring for the LED sequential function?

No. The sequential LED module ties directly into your existing turn signal harness at the mirror. No dash rewiring or relay upgrades required — it plugs into what you've got.

What's the weight difference compared to OEM mirrors?

This mirror is designed as a direct replacement without adding significant mass to your hood. Exact weight savings depend on your OEM baseline, but manual mirrors are lighter than power units across the board.

Will the manual adjustment mechanism freeze up in winter?

The mechanism uses a sealed linkage that resists moisture intrusion, but extreme cold or salt buildup can stiffen any manual system. Regular cleaning and light lubrication at hinge points will keep travel smooth year-round.
