RD5 Series HID Replacement Bulbs (D1S / D3S)

When considering a hid headlight replacement, many drivers debate whether to stay with HID or switch to LED. While HID technology was once the standard, it suffers from key drawbacks: high heat, fragile arc tubes, and slow warm-up times. These issues often lead to frequent hid bulb replacement and higher long-term costs.

A modern hid to led replacement like the Hawkglow RD5 addresses these weaknesses with advanced LED technology. Delivering 80W / 24,000LM at 6500K, RD5 bulbs provide instant illumination, sharper visibility, and a more uniform beam pattern. Unlike typical hid replacement headlights that last only 2,000–3,000 hours, RD5 LEDs are rated for up to 50,000 hours and feature IP68 durability for all-weather reliability.

Upgrading from HID to LED is not just brighter—it’s safer, longer-lasting, and more efficient. For drivers seeking the most advanced hid replacement bulbs, the RD5 sets a new benchmark in performance and reliability.

How to Choose the Correct HID Replacement Bulb?

Choosing the right hid bulb replacement is critical to ensure proper fit and performance. The Hawkglow RD5 series covers the two most common HID socket types: D1S and D3S. While both offer identical performance in brightness and lifespan, the difference lies in the socket design and the vehicles they fit.

Most European luxury sedans use D1S, while D3S is often found in newer SUVs and crossovers. The easiest way to confirm your type is to check your vehicle’s owner’s manual, inspect the label on your existing bulb, or consult your dealer. By verifying this information before purchasing, you’ll guarantee the perfect hid headlight bulb replacement with RD5.

👉 Pro tip: If your vehicle currently uses HID, simply match the bulb type (D1S or D3S) with RD5 LED, and you’ll enjoy a seamless upgrade.
