Will this lens fit my existing 12V surface‑mount taillight?

Compatibility depends on the shape and mounting pattern of your current taillight housing. The 89‑187 is a universal compact lens intended to suit many surface‑mount housings, but you should compare dimensions and mounting screw locations before purchasing.

• Overall lens size: about 8‑5/8" long × 3‑3/4" high × ~1‑3/4" deep.
• Designed for 12‑volt surface‑mount taillight fixtures.
• Universal style — verify hole spacing and bezel shape on your housing.

How easy is it to install the replacement lens?

Installation is typically quick and uses the existing taillight screws or clips. You’ll remove the old lens, check the gasket or seal, position the new lens over the lamp and socket, then refasten the mounting screws to secure it.

• No electrical changes needed if bulb and base remain intact.
• Standard screwdriver or small socket set usually required.
• Inspect or replace any worn gasket to maintain a weatherproof seal.

What are the material and color characteristics to expect?

The lens is molded in red to provide the correct color filtration for taillight output. Materials commonly used for replacement lenses are impact‑resistant plastics engineered for outdoor use; check for UV resistance if fading is a concern in your application.

• Red color matches standard taillight visibility requirements.
• Durable plastic construction for outdoor exposure.
• Transparent textured finish to diffuse light evenly.

How do I verify measurements and avoid incorrect orders?

Measure the existing lens or housing before ordering: length, height, depth, and mounting hole centers matter most. Cross‑reference those numbers with the 89‑187 dimensions and inspect the shape against product photos or your current lens.

• Length: 8‑5/8" (approx.).
• Height: 3‑3/4" (approx.).
• Depth: listed as 1‑3/4" in description; features list shows 2‑1/8" depth—confirm against your housing.
• Confirm screw hole placement and bezel contour prior to purchase.
