Why I Chose Hikari Ultrafocus LEDs
I wanted a lighting solution that was brighter and more energy-efficient than the stock halogen bulbs. The Hikari Ultrafocus LEDs promised superior brightness, longer lifespan, and better beam focus, which sounded perfect for my classic SL 500. Plus, their compatibility with the H4/9003 socket was a must since that’s what my car uses.
Compatibility With My 1997 Mercedes SL 500
The first step I took was confirming the bulb type. The SL 500 from ’97 uses H4/9003 bulbs, which means I needed a dual-beam headlight capable of handling both low and high beams. The Hikari Ultrafocus bulbs fit this requirement perfectly. Always double-check your vehicle’s manual or existing bulbs to avoid any mismatch.
Brightness and Beam Pattern
One of my main concerns was whether the LED bulbs would provide a clean, focused beam without causing glare to other drivers.
