LED Bulb Type 1157 (Pair) - LG5102

LED Bulb Type 1157 (Pair) – LG5102

Compact, efficient and road-focused, the LED 1157 replacement bulb pair LG5102 gives you a sharp, consistent rear light output with almost no heat and far lower current draw than standard filament bulbs. Designed for 12–30 V systems, it drops straight into existing 1157 / BAY15D twin-contact holders on cars, tractors and trucks. EMC approved, so it won’t upset sensitive vehicle electronics or radio systems.

The 1157 bulb is a workhorse in older and current fleets: tail / brake, rear position / stop, and various signal functions. This LED upgrade keeps the familiar fitting but replaces the fragile filament with solid-state electronics and a controlled light pattern. You get 450 lm on the high (brake) function and 100 lm on the low (tail) function, which means a crisp, instant-on brake light and a clearly visible running light that doesn’t glare.

Because the LG5102 runs on 12–30 V, it’s suitable for both light vehicles and heavy plant, without needing resistors or separate versions. The integrated electronics manage the voltage range and current, so output stays stable even with alternator ripple and long cable runs. That’s helpful on trailers, agricultural kit and older wiring looms where volt drops are common.

Installation is straightforward. This is a direct plug & play 1157 LED bulb with the same bayonet base and twin contacts, so it slots into existing holders in minutes. At 20.4 × 46.8 mm, it’s compact enough for most lamp housings where space is tight, including older steel-bodied lamps and combination rear lights. Once fitted, the LED core offers long service life, which cuts downtime on fleets and saves you repeated bulb changes.

Key Features

• Direct 1157 / BAY15D replacement – designed for twin-contact 1157 sockets, ideal for tail / brake or position / stop functions.
• Dual output levels: 450 lm / 100 lm – strong, instant-on brake function and a steady, visible tail light for safer signalling.
• Wide voltage range 12–30 V – one part covers cars, vans, 4x4s, tractors, trailers and trucks on 12 V or 24 V systems.
• Low power draw: 4.4 W / 0.9 W – significant reduction in current compared with filament bulbs, helpful on long runs and multi-lamp circuits.
• Compact size: 20.4 × 46.8 mm – fits in most OE housings without modification, including older metal-bodied and sealed rear lamps.
• EMC approved – engineered to minimise electrical noise, protecting radios, control modules and CAN-based systems.
• Plug & play installation – no rewiring for standard 1157 holders; remove old bulb, insert LED, test, and the job is done.
• Solid-state LED design – vibration-resistant and proven on working vehicles that see rough tracks, field work and daily stop–start use.
• Pair supplied – each kit includes 1 × pair of 1157 LED bulbs (LG5102) for consistent left/right replacement.

Ideal Applications

• Cars and 4x4s using 1157 bulbs for rear tail / brake or position / stop lights.
• Light commercial vans and pickups needing a durable LED rear bulb upgrade.
• Agricultural tractors and telehandlers where vibration and long hours quickly kill filament bulbs.
• Plant, trailers and low loaders on 12 V or 24 V systems that share 1157 rear lamp housings.
• Small trucks and municipal vehicles where reliability and low maintenance are essential.

Why Choose LED-Global Lighting
