Round Marker Lights, Clearance Lamps & Signals

Compare penny lights, 2-inch and 2½-inch clearance/marker lamps, light kits, watermelon-style options and 4-inch turn-signal and back-up lights. Explore red, amber, clear-lens and dual-colour versions.

Match the required lighting function and actual mounting dimensions, then check voltage, connections and included parts.

Choose the Right Round Light

Compare the actual size

Penny, 2-inch, 2½-inch and 4-inch listings require different fitment checks. Compare housing dimensions, mounting opening, depth and connector clearance. A round face or matching nominal diameter alone does not confirm a replacement fits.

Match function & output

Marker/clearance lamps, turn signals and back-up lights perform different jobs. Check the exact lamp’s function and emitted colour. Dual-function and dual-colour describe different features, so review the model’s operating modes and wiring.

Check lamps versus kits

A lamp-only listing and a kit may supply different components. Confirm quantity, grommet, plug and mounting hardware before ordering. Check voltage and connections for the selected model; heated and auxiliary options need their own installation checks.

Round Marker Light FAQs

Will any 2-inch round light fit my existing mount?

Compare the exact light dimensions, required mounting opening, retention method and available depth. Check the specified grommet or bracket and connector clearance rather than relying only on the nominal diameter.

Can a round marker light replace a turn signal or back-up lamp?

Choose a lamp explicitly listed for the function required. This assortment includes separate clearance/marker, turn-signal and back-up products. Round shape, LED count and wire count alone do not establish interchangeability.

Does a clear lens produce white light?

No. Clear lenses can be paired with amber or red LEDs, as well as white LEDs. Check the selected LED output colour, lens colour and lighting function before ordering.

What comes with the 9 LED 2-inch Round Light Kit?

The 9 LED 2-inch Round Clearance/Marker Light Kit listing specifies one light, a grommet (#31505) and a male plug pigtail (#34210), with 12V DC operation. Those included parts should not be assumed for other round lights or lamp-only listings.

Are dual-function and dual-colour lights wired the same way?

Do not assume so. Dual-function describes stated operating functions or brightness modes, while dual-colour describes two LED colours. Follow the exact product’s voltage, connection instructions and use restrictions for any secondary or auxiliary output.
