International 4700-4900 Lights

Frequently Asked Questions About International 4700-4900 Lights

Will these lights fit my specific year International 4700 or 4900 truck?

Most aftermarket lights for International 4700-4900 trucks are designed to fit models from 1989 through 2002. However, there were minor changes in mounting points and wiring harnesses between model years. We recommend checking the specific product description for year compatibility or contacting our support team with your OEM number to ensure proper fitment. Pay special attention if you have a 1995-1997 model, as these years had unique headlight bucket designs.

Do I need special tools or professional installation for headlight replacement?

Basic headlight replacement typically requires standard hand tools including Phillips and flathead screwdrivers, 10mm and 13mm sockets, and wire crimpers for any connector modifications. The process usually takes 30-45 minutes per side. However, if you're installing LED conversions or HID kits, you may need additional wiring harnesses and potentially a drill for mounting ballasts. Many customers successfully complete the installation themselves, but electrical modifications beyond plug-and-play replacements may benefit from professional installation.

What's the difference between sealed beam and composite headlights for these trucks?

International 4700-4900 trucks came with either 7-inch round sealed beam headlights or rectangular composite assemblies, depending on the model year and configuration. Sealed beam units are one-piece designs where the entire unit is replaced, while composite headlights have replaceable bulbs. Pre-1995 models typically use dual 7-inch round sealed beams, while later models often feature the rectangular composite style. Check your current setup before ordering, as the mounting systems are not interchangeable without significant modification.

Are LED upgrades worth it, and will they work with my truck's electrical system?

LED headlights offer 3-5 times more light output than standard halogen bulbs while drawing less power, making them popular upgrades. However, some International 4700-4900 trucks may require load resistors or electronic flasher relays to prevent hyperflashing with LED turn signals. Most quality LED headlights are true plug-and-play replacements, but older trucks (pre-1995) might need polarity adapters. The improved visibility and 50,000+ hour lifespan typically justify the higher initial cost for drivers who use their trucks regularly.

Why do my new headlights fog up, and how can I prevent it?

Fogging in new headlights often occurs due to improper sealing during installation or damaged weather seals. When installing, ensure all rubber gaskets are properly seated and apply dielectric grease to connection points. Some aftermarket lights may have inadequate venting - look for units with proper breather caps or vents. If fogging persists, check that the headlight bucket drain holes aren't clogged, as water accumulation in the housing area is a common issue on International 4700-4900 trucks, especially on work trucks exposed to frequent washing.
