Physical Compatibility:
Ensure the LED bulb has the same base type (H4/9003) as your original halogen bulb. Most LED replacements are designed to fit H4 sockets, but check the specifications to confirm.
Beam Pattern and Focus:
LEDs emit light differently than halogen bulbs. For proper road illumination and to avoid blinding other drivers, choose LEDs with built-in projectors or reflectors that mimic the halogen bulb’s filament placement. Poorly designed LEDs may scatter light incorrectly.
Legal Compliance:
Regulations vary by region. Some countries or states prohibit aftermarket LED replacements in halogen headlight housings due to non-compliant beam patterns. Check local laws to avoid fines or failed inspections.
Electrical Compatibility:
LEDs draw less power than halogens. Some vehicles may trigger error messages or flickering due to reduced current. Use CANBUS-compatible LEDs or add load resistors to resolve this.
Heat Dissipation:
High-quality LED bulbs include heat sinks or fans. Ensure your headlight housing has enough space for these components to prevent overheating.
Performance Benefits:
LEDs last longer, consume less power, and often produce brighter, whiter light than halogens.
Recommendation:
Purchase reputable LED bulbs explicitly designed for H4 halogen replacements, verify legal compliance in your area, and consider professional installation to ensure proper alignment and functionality.
(Note: Always prioritize safety and legality over aesthetics or cost savings.)
