International 9300/9370 Lights

Frequently Asked Questions About International 9300/9370 Lights

Will these lights fit my specific year International 9300 or 9370?

Most aftermarket lights for International 9300 and 9370 models are designed to fit trucks manufactured from 1987 through 2007. However, there are some variations between early models (1987-1999) and later models (2000-2007), particularly in headlight bucket sizes and turn signal configurations. Always verify the specific year range listed for each product, and when in doubt, contact us with your OEM number for exact fitment confirmation.

Are LED upgrade options available, and will they work with my truck's electrical system?

Yes, LED upgrades are available for most International 9300/9370 light positions including headlights, turn signals, and marker lights. These LEDs are designed to work with 12V systems without requiring resistors or special adapters. However, some older trucks (pre-1995) may experience hyper-flashing with LED turn signals, which can be resolved by installing a compatible LED flasher relay. LED headlights typically draw less power than stock halogen bulbs, so no wiring upgrades are needed.

How difficult is it to replace the headlights, and what tools do I need?

Headlight replacement on International 9300/9370 trucks is straightforward and typically takes 30-45 minutes per side. You'll need basic hand tools including a Phillips screwdriver, 10mm and 13mm sockets, and possibly a trim removal tool for the bezel. The process involves removing the grille (held by 6-8 screws), disconnecting the wiring harness, removing 3-4 mounting bolts per headlight assembly, and reversing the process with new lights. No cutting or drilling is required for direct replacement units.

What's the difference between OEM-style and aftermarket lights in terms of quality and longevity?

OEM-style replacement lights typically use similar materials and construction to original equipment, featuring glass lenses and metal housings that can last 5-7 years. Aftermarket options vary widely - premium brands offer polycarbonate lenses with UV coating and sealed beam construction that often outlast OEM lights. Budget options may use thinner plastic that yellows or cracks within 2-3 years. Look for lights with DOT/SAE certification and sealed, waterproof connections for best longevity.

Do marker lights and turn signals come with pigtails, or will I need to splice wires?

This varies by manufacturer and product line. About 60% of replacement marker lights and turn signals come with 12-18 inch pigtails with standard 2 or 3-pin connectors that match OEM plugs. The remaining 40% require splicing or purchasing separate pigtail adapters. Product descriptions should specify whether pigtails are included. If splicing is required, use weatherproof butt connectors and heat shrink tubing to prevent corrosion issues common in these exposed locations.
