This Dacall headlight switch is engineered for a range of GM full-size trucks and SUVs from the early 2000s and later model exceptions, ensuring wide compatibility when replacing worn or broken controls.

How easy is installation and what comes in the box?

Installation is plug-and-play for matching vehicles, requiring no splicing or special tools. Dacall includes a small removal tool to help extract the old switch and guides the user to snap the new unit into the factory location for a clean replacement.

What are the build quality and functional controls like?

Dacall builds this switch from durable ABS plastic to resist heat and normal wear, aiming for a long service life in demanding automotive environments. The control offers a tactile, responsive feel for selecting headlight modes and adjusting instrument panel illumination without a laggy or flimsy action.

• Durable ABS housing for heat and wear resistance.
• Responsive rotary/action feel for low beam, parking, dome and fog lamp control.
• Includes dashboard backlighting adjustment for instrument visibility customization.

How should I verify compatibility before buying?

Because GM used multiple switch variants across model years and trim levels, a visual and part-number check prevents returns and fitment problems. Inspect your current switch’s face, connector shape and OEM number to match it against the Dacall listing and included replacement part numbers.

• Compare the OEM number printed on your original switch to the Dacall replace list (e.g., 15176678, 15198374, D1595G).
• Confirm the connector pin count and orientation match your vehicle harness.
• Check physical dimensions and mounting orientation against your dash opening.

Who this is for: Owners and DIY mechanics driving compatible GM trucks and SUVs from the 2003–2007 era who need a cost-effective, OEM-alike replacement for a failing headlight or fog-light control. This unit is suited to anyone comfortable doing a simple dash trim removal and plug-and-play swap, and to fleet managers or repair shops looking for a dependable aftermarket option that mirrors factory functionality. If you’re unsure about fitment, compare the part numbers and connector style on your existing switch or contact Dacall support for assistance before ordering.
