LED Bulb Type BAY15D (Pair) - LG5111

LED Bulb Type BAY15D (Pair) – LG5111

This BAY15D LED bulb pair is engineered as a robust upgrade from standard dual-filament bulbs in cars, tractors and trucks. You get strong light output, low current draw and clean operation on 10–30 V systems, all in a compact plug & play package. EMC approval keeps your radios and electronics quiet.

These BAY15D LED bulbs are designed for professional users who need reliable dual-intensity lighting: one level for tail or position, a stronger level for brake or signal. With 450 lm / 100 lm output and 4.4 W / 0.9 W power draw, you get a clear, visible signal without loading the electrical system, even on older vehicles or mixed fleets. They’re a simple way to modernise lighting on work vehicles without changing lamp housings.

The wide 10–30 V operating range covers both 12 V and 24 V systems, so the same pair works across cars, vans, tractors, forklifts and trucks. That reduces stock complexity and mistakes in the field. The compact 20.4 × 46.8 mm body is close to traditional bulb dimensions, which helps with fitment in tight housings or enclosed rear clusters.

Installation is straightforward. The BAY15D base is a direct mechanical replacement, so you simply remove the old bulb and fit the new LED – true plug & play. Because the bulbs are EMC approved, they’re engineered not to interfere with vehicle electronics when installed correctly. On some vehicles with lamp-out detection, you may need load resistors; your auto electrician will know this from the vehicle spec.

Key Features

• BAY15D dual-contact base – direct replacement for standard BAY15D dual-filament bulbs, no mechanical modification needed
• Wide voltage range: 10–30 V – suitable for both 12 V and 24 V vehicles across mixed fleets
• Dual-power output: 4.4 W / 0.9 W – supports two intensity levels (e.g. brake/tail), reducing energy use versus halogen
• High light output: 450 lm / 100 lm – bright primary level with a clearly distinct secondary level for safe signalling
• Compact size: 20.4 × 46.8 mm – fits most existing lamp housings where standard BAY15D bulbs are used
• Plug & play installation – simple bulb swap, no rewiring for correctly wired BAY15D holders
• EMC approved – designed to minimise electrical interference with radios and onboard electronics
• Low current draw – eases load on alternators and wiring, especially useful on older or heavily accessorised vehicles
• Sold as a matched pair – 1 × pair of BAY15D LED bulbs (LG5111) included for consistent left/right performance

Ideal Applications

• Passenger cars and vans using BAY15D bulbs for tail, brake or rear position lights
• Agricultural tractors and implements needing durable, low-draw LED rear lighting
• Trucks and trailers running mixed 12/24 V fleets with BAY15D lamp holders
• Construction and plant equipment where vibration-resistant LED bulbs are preferred over fragile filaments
• Material-handling vehicles (e.g. forklifts, yard tractors) upgrading to clearer signalling with minimal downtime
