If you’re planning to enhance the visibility of your 1988-1998 Chevy truck by performing the 4 High Beam Headlight Mod, it’s essential to gather the correct parts before you begin. This modification allows all four headlight beams—both low and high beams—to operate simultaneously, giving you a broader and brighter field of vision at night. Here’s a breakdown of the parts you’ll need to successfully complete this mod.

1. Relay Kit
A relay kit is the cornerstone of the 4 High Beam Headlight Mod. The relay ensures that the low beams remain on when the high beams are activated, without overloading the headlight switch. The relay kit typically includes:
- A 12V automotive relay (commonly a 4-pin or 5-pin relay).
- Relay socket or pigtail for easy wiring.
- Inline fuse (usually 15-20 amps) to protect the circuit.
2. Electrical Wire
You’ll need additional electrical wire to connect the relay to the existing headlight wiring. Ensure that the wire is:
- Automotive-grade and suitable for use in an engine compartment.
- 16-18 gauge, which is standard for headlight circuits.
3. Wire Connectors

Various wire connectors are necessary for splicing and connecting the new wires to the existing system. These might include:
- Butt connectors for joining wires.
- Spade connectors to attach wires to the relay.
- T-tap connectors to easily tap into existing wires without cutting them.
4. Crimping Tools
To secure the wire connectors properly, you’ll need a good crimping tool. This tool ensures that the connections are tight and reliable, preventing electrical issues down the road.
5. Wire Strippers and Cutters
A wire stripper is crucial for removing the insulation from the wires without damaging them. Wire cutters are needed to trim wires to the appropriate length.
6. Electrical Tape or Heat Shrink Tubing
Once you’ve made your connections, it’s important to insulate them properly to prevent shorts or corrosion. Electrical tape is the most common choice, but heat shrink tubing offers a more durable and professional finish.
7. Zip Ties
Zip ties help to keep the wires organized and secure within the engine compartment. This reduces the risk of wires getting tangled or coming into contact with hot engine components.
8. Test Light or Multimeter

A test light or multimeter is handy for checking the continuity of your connections and ensuring that the wiring is correct before finalizing the installation.
9. Screwdrivers and Basic Hand Tools
You’ll need a set of screwdrivers and possibly other basic hand tools to remove and replace components like the headlight assemblies and to access the wiring.

10. Additional Fuses
While your relay kit might include a fuse, having some extra automotive fuses on hand (matching the amp rating of the original) is a good idea, just in case something goes wrong.
11. Headlight Upgrade Bulbs

While you’re modifying your headlights, you might consider upgrading to brighter or higher-quality bulbs. This isn’t necessary for the mod, but it can further enhance your visibility.
Summary
To successfully complete the 4 High Beam Headlight Mod on your 88-98 Chevy truck, you’ll need a relay kit, electrical wires, connectors, and a few essential tools. Proper preparation with these parts will make the installation process smoother and ensure that your headlights function optimally, providing the best possible visibility for nighttime driving.
