Philips H4 Headlamp Relay with Connector

The Philips H4 Headlamp Relay with Connector is a premium quality automotive relay specially designed for H4 bulb headlight systems. If your H4 headlights are dim, flickering, or your connector is burnt or melted — this relay is the perfect plug-and-play solution. 
It draws full power directly from the battery and delivers it to your H4 headlight bulb for maximum brightness, longer bulb life, and better night driving safety.

WHAT IS AN H4 HEADLAMP RELAY & WHY DO YOU NEED IT?
━━━━━━━━━━━━━━━━━━━━━━━━━━

H4 is one of the most commonly used headlight bulb types in Indian 
cars. It is a dual filament bulb that controls both high beam and 
low beam from a single bulb. The factory H4 wiring in most cars is 
thin and carries limited current — this causes:

- Dim H4 headlights on both high and low beam
- Flickering headlights while driving at night
- Melted or burnt H4 connector
- H4 bulb burning out frequently
- Poor visibility on highways and dark roads

The Philips H4 Relay with Connector solves all of this by:

- Bypassing weak factory H4 wiring
- Drawing full power directly from the battery
- Delivering complete 12V to your H4 bulb
- Protecting the H4 connector from overheating
- Improving brightness up to 30-40% instantly
- Extending H4 bulb life significantly
