LED Bulb Type 7740 (Pair) - LG5103

LED Bulb Type 7740 (Pair) – LG5103

Upgrade from dull halogen to crisp, modern 7740 LED bulbs without reworking your wiring. The LG5103 pair delivers 620 lm of clean light at just 6.3 W, ideal for professional and agricultural vehicles that need reliability every day. Wide 10–30 V input and EMC-approved electronics make these a safe, stable choice for mixed 12 V and 24 V fleets.

These 7740 LED bulbs are designed as a plug & play replacement where a 7740 type bulb is specified. No resistors, no rewiring, no drama. You get strong, efficient light output from a compact body measuring 20.4 × 46.8 mm, so they sit neatly in existing housings on cars, tractors and trucks.

Because they run on 10–30 V, they suit both 12 V passenger vehicles and 24 V commercial or agricultural systems. That makes them especially useful in mixed fleets where you want one proven part number on the shelf. Power draw is just 6.3 W per bulb, yet you still get around 620 lumens, so you cut load on looms and switches while improving light quality.

Electromagnetic compatibility is covered too. The LG5103 is EMC approved, so it’s designed not to interfere with radios, communication equipment or control systems when installed correctly. That’s important on modern tractors and trucks packed with electronics. Installation is straightforward: remove the old bulb, insert the LED replacement, check polarity if needed, and you’re back in service in minutes.
