AAIWA 4x6-inch LED headlights

If you’re replacing a sealed-beam headlight and want high and low beams plus a daytime running light, this AAIWA pair is aimed at that specific job. The 4x6-inch format and standard 3-pin H4 plug may make it a straightforward replacement in a vehicle with matching headlight dimensions and wiring. It’s less of a universal upgrade than the broad fitment wording suggests: the actual housing and pin layout matter, so identify those before choosing it.

Quick overview

The package includes two LED headlights, each with high and low beams and a DRL. The listing specifies 4,500 lumens for high beam and 2,500 lumens for low beam per light, with a yellow-and-white colour designation in the product name. That gives you the essentials for replacing a pair, rather than buying a single lamp, while retaining both beam settings.

The manufacturer also lists an IP68 waterproof rating, a heat sink for cooling and a breathing hole intended to help drive away moisture. It claims a lifespan above 50,000 hours, but that figure is a product claim, not a guarantee of service life in every vehicle or climate. Given its design, this is best considered when your existing lights use a 4x6 sealed-beam format—not simply because your vehicle is a truck.

Best use cases

These lights are intended for vehicles with 4x6-inch headlights, including the listed Chevy S10 Blazer model years 1994–1997 and some Peterbilt, Kenworth, Freightliner and Probe applications. The listing also names HID Xenon replacements H4651, H4652, H4656, H4666 and H6545. Treat those references as a starting point, they don’t establish that every trim or wiring setup will match.

For example, if a vehicle with the specified sealed-beam housing needs both lamps replaced, the pair format and high/low-beam function are relevant. Ten en cuenta que the listing warns that non-standard vehicle pins may require a separate H4 9003 wiring harness. It also suggests an H4 headlight relay if existing lights are dim or malfunctioning, so don’t assume a new lamp alone will address an electrical issue.

Tips for day-to-day use

Before ordering, compare the existing lamp’s 4x6 dimensions and connector with the vehicle’s actual setup. The stated plug is a 3-pin H4, a mismatch may mean additional wiring work rather than the advertised plug-and-play installation. After fitting, check that both high and low beams and the DRL operate as expected. The listing provides no vehicle-specific installation steps, so installation difficulty may depend on access and wiring in your vehicle.

It suits you if you need a two-light replacement in a confirmed 4x6 housing and want LED high/low beams with DRL. No te encajará si your headlights use another size or you need a guaranteed fit based only on the vehicle name. A basic like-for-like sealed-beam replacement may be the simpler route if you don’t need the LED and DRL features, for a more demanding upgrade, first establish that the vehicle’s wiring and beam pattern are suitable.

Buying questions

Are two headlights included? Yes. The package is listed as two 4x6-inch LED headlights.

Does it have both high and low beams? Yes. The listing specifies high beam and low beam, as well as a daytime running light.

Will it fit any vehicle with a 4x6 headlight? The product is described for 4x6 applications, but connector pins and vehicle fitment can vary. Confirm the housing and 3-pin H4 connection rather than relying on the broad fitment claim alone.

Is it worth it?

This pair makes the most sense when your vehicle has the matching 4x6 sealed-beam housing and 3-pin H4 wiring, and you want LED lighting with a DRL in one replacement set. The stated output figures and included pair are useful points of comparison, but fitment is the deciding factor here. If your connector is non-standard, your lights are already dim because of an electrical fault, or you can’t confirm the housing size, resolve that first, otherwise, the plug-and-play description may not reflect the work your vehicle needs.
