Upgrading your Chevy Silverado 2500 3500’s headlights is one of the best ways to improve nighttime visibility and safety. The Lasfit Pro-DC Series is a custom-fit LED headlight replacement kit designed specifically for the 2020–2026 Chevy Silverado 2500 and 3500.
This kit includes:
- A pair of high-performance LED headlight bulbs (55W, 5500LM each)
- Integrated dust covers with built-in cooling fans
The left side shows the brightness of the LED low beams, and the right side shows the brightness of the LED high beams.
With its dual heat dissipation system and vehicle-specific design, the Pro-DC Series offers durability, brighter light output, and a 100% plug-and-play installation—no modification required.
In this guide, we’ll walk you step by step through replacing the low beam bulbs using a removed Silverado headlight assembly.
Step-by-Step Installation Guide

Locate the Low Beam Position
Put on gloves and find the low beam mounting position on your headlight assembly. -
Remove the OEM Dust Cover

Take Out the OEM Halogen Bulb

Disconnect the OEM Bulb from the Wiring
One-hand method: Press the clip on the H11 halogen bulb connector with your thumb while pulling the bulb out with your other fingers.

Connect the LED Bulb to the Power Harness
Snap the clip on the factory power wire onto the protruding tab of the LED bulb’s connector to secure the connection. -
Insert the LED Bulb into the Socket
Align the LED bulb tabs with the headlight socket and push the bulb straight in. -
Lock the Bulb in Place
Press down and rotate the bulb clockwise until it locks firmly into the socket. -
Confirm Proper Orientation
The LED chips should naturally sit at the 3 o’clock and 9 o’clock position, with the power wire pointing straight down at 6 o’clock. No adjustment is needed. -
Tuck the Wiring Inside
Carefully place the wiring and connectors inside the new dust cover. -
Install the New Dust Cover
Make sure the markings and vent hole on the dust cover face downward, then press the dust cover firmly into the assembly.
Found that the OEM headlight housing tabs are of different lengths.
The tabs on the LED bulb also vary in length.
Ensure that the LED bulb tabs align with the slots in the housing.
Do You Need to Remove the Headlight Assembly on 2020–2026 Chevy Silverado 2500 & 3500?
No, you don’t.
For the driver side, turn your steering wheel fully to the right to create more space between the wheel and the fender. Remove the fender screws with a screwdriver, and you’ll have enough room to access the headlight assembly from the fender area.
For the passenger side, simply repeat the process in the opposite direction.
