Automotive halogen bulb BLOW H3 12V 55W (model 5047#)

BLOW H3 12V 55W (model 5047#) is a single-filament automotive halogen bulb designed for standard vehicle lighting applications that require an H3 type lamp. The bulb operates at 12 volts and 55 watts, delivering conventional halogen illumination suitable for headlights and auxiliary lamps where H3 bulbs are specified. Its compact H3 format and clear glass envelope provide a focused beam pattern when used with compatible reflectors and housings.

Advantages

The bulb’s single-filament design simplifies installation in H3 sockets and is compatible with most vehicles and auxiliary lighting systems that accept H3 lamps. It provides a balance of luminous flux and power consumption typical for 12V/55W halogen automotive bulbs, allowing straightforward replacement of worn or failed lamps.

How to use

Ensure the vehicle electrical system is switched off and the headlight or lamp assembly is cool before replacing the bulb. Access the lamp housing according to the vehicle manufacturer’s instructions, remove the protective cover if present, and release the old H3 bulb from its socket or retaining clip. Handle the replacement bulb by its base without touching the glass envelope; oils from skin can shorten bulb life. Insert the new H3 bulb into the socket or clip until it seats securely, reassemble the lamp housing and protective covers, and test the light function before driving.

Usage recommendations

For safe operation and optimal lifespan, avoid touching the glass with bare hands and verify correct seating in the H3 socket. Replace bulbs in matching pairs where appropriate to maintain uniform light output. If the vehicle uses additional lighting controls or electronic modules, consult the vehicle manual to confirm compatibility before installation.
