2 Del. Admin. Code § 2268
Whereas the size and design of woodsplitters and wood chippers and the nature of their work make it impractical to require turn signals, stop lights, tail lights and license plate lights on them, the following policy is implemented effective immediately.
All log (wood) splitters and wood chippers must be titled and registered as a trailer.
The requirement for all lights are waived during daylight hours, if the stop lights and directional signals on the towing vehicle are visible to a trailing vehicle.
