Advice from real cruisers

These side-pin G4 LED bulbs easily replace power-hungry 10W or 20W halogen bulbs on your boat or RV, and fit even the slimmest overhead downlight fixtures.

They can operate on 12V AC or DC, or 24VDC.

Thanks to their constant-current circuitry, they are not only multi-voltage capable, but this also allows them maximize the output and color temperature of the 10 high-output LEDs. You won't be disappointed with the output of these bi-pin G4 LED bulbs. There are none brighter or longer lasting in this form-factor.

These bulbs can operate fine on reversed polarity, and also have a built-in PTCC thermal-foldback fuse and a Transient Voltage Suppressor to prevent damage from overcurrent, voltage spikes, or over-heating.

They are also dimmable on DC PWM dimmers of the type commonly found on many boats and RVs.

Everyone here is a current or past cruiser — we’ve docked short-handed, re-rigged at anchor, and chased 12V gremlins too. Not sure this is the right fit for your boat? Send us your question before you order and we’ll give you a straight answer.

Check fit before ordering

Base and pins: match the socket, contact count, pin position, orientation, and spacing to the lamp being replaced.
Electrical fit: verify the DC voltage range, polarity requirements, and compatibility with existing dimmers.
Physical clearance: compare the full bulb diameter, height, pin length, lens, and reflector clearance.
Light output: choose the intended color, temperature, beam pattern, and navigation or cabin-light use.
