- The sequential sweep must finish within the vehicle’s flash cycle.
- Light guides should glow evenly; brake lamps must be clearly brighter.
- Smoked lenses can cut output — check local rules.
- Sealing, OEM-style plugs and hyper-flash prevention reduce returns.
Sequential or dynamic tail lights are one of the easiest upgrades to sell: they change the rear of the car instantly and install without permanent modification. For wholesale buyers, the details below separate a reliable SKU from a returns problem.
Animation and timing
The sweep should complete within the flash cycle of the vehicle. Ask for a video of the indicator and start-up animation running on the actual model.
Brightness and uniformity
Light guides should glow evenly with no hot spots. Brake lamps must be clearly brighter than the position lamp. Check that reverse lamps provide usable light, not just styling.
Lens options
Clear, smoked and red lenses appeal to different customers. Smoked lenses can reduce output; confirm what is permitted in your market.
Sealing and connectors
Tail lamps sit in the spray zone. Look for full-perimeter seals, OEM-style plugs and included load resistors or adapters for hyper-flash prevention.
Range planning
- Start with best-selling platforms in your market.
- Pair headlights and tail lights for the same model to raise basket value.
- Keep spare adapters for quick after-sales support.
