Partsam Boat Trailer Guide-On Post Lights Black, 2pcs DOT Approved IP67 Waterproof Tail/Turn/Brake

If you load, tow or back a boat after dusk, clear visual reference points and functioning trailer lights are essential. The Partsam 2pcs Boat Trailer Guide on Post Pipe Light Set combines high-output SMD LEDs with a compact, weatherproof housing to mark the trailer’s left and right posts while providing full tail/turn/brake functions. Designed to fit standard 2" PVC guide posts and rated IP67, these lights are built to resist spray and brief submersion while making night launches quicker and less stressful.

How do these guide-post lights improve night launching and retrieval?

These post lights create obvious vertical beacons that show the trailer’s edge from the vehicle cab and on the ramp. Their bright SMD LEDs cut through low light and reflect off the water and hull, helping you center the boat and avoid contact with the post or trailer frame. They also integrate conventional tail/turn/brake functions so the trailer is visible to other road users.

• Patented SMD LEDs deliver stronger, consistent illumination compared with standard LEDs
• Dual-purpose: guide-post marker plus full tail/turn/brake lighting
• Differentiated left and right markers simplify alignment on narrow ramps

Will these lights survive saltwater, rain and trailer spray?

Yes — the housings are engineered to meet IP67 ingress protection, which resists dust and protects against temporary immersion. Corrosion-resistant materials and sealed wiring help the assembly tolerate routine exposure to spray, freshwater, and occasional saltwater environments when rinsed and maintained. This makes them suitable for most boating locations when proper post-installation care is followed.

• IP67-rated housing resists water and dust intrusion
• Durable construction minimizes salt and moisture damage
• Recommended to rinse with fresh water after salt exposure

How do I install the Partsam guide-on post lights on my trailer?

Installation is straightforward and compatible with common 2" PVC guide-on posts (2-3/8" outside diameter). The wiring follows standard color codes: white ground, black low/marker, red high/stop/turn (and white/black for the top guide light positive where applicable). The set includes spare mounting screws and fits over or onto the pipe using the provided fasteners so you can secure them firmly to the post.

• Fits standard 2" PVC guide posts (2-3/8" OD)
• Wiring: white = ground; black = low/marker; red = high/stop/turn
• Includes mounting screws; use screw positions 1 or 2 for secure fastening

What functions and performance can I expect from these lights?

The kit provides full-function tail, turn and brake lighting combined with a bright guide light on the post for improved visibility. The SMD LED elements offer greater brightness and longer service life compared with older filament or standard LED modules. DOT approval ensures the lamps meet common road-visibility standards when installed correctly.

• Full tail, brake and turn signal capability built into the post light set
• High-brightness SMD LEDs for clearer visibility at night
• DOT-approved design for compliant road use when wired properly

Who is this for? Boaters, anglers and trailer owners who regularly launch or retrieve watercraft after dark — as well as anyone who wants clearer roadside visibility while towing. This Partsam two-piece guide-on post light set suits owners of ski boats, fishing boats, sailboats and small to medium trailers that use standard 2" PVC guide posts and need a reliable, weatherproof lighting solution that combines marker and brake/turn functions.
