Let’s face it—stock Honda Acty lighting is… not great. Dim headlights, aging wiring, and faded housings are common problems on these 25+ year-old kei trucks and vans. Whether you're restoring visibility for safety or adding a clean, modern look, upgrading to LED lighting is one of the easiest and most impactful mods you can make.
In this guide, we’ll show you how to modernize your Acty’s lighting—headlights, taillights, signals, and more—with reliable LED upgrades and practical install tips.
1. Why Upgrade to LED Lighting?
-
Brighter output = better visibility at night and in poor weather
-
Lower power draw = less strain on your battery and alternator
-
Longer lifespan = no more burnt bulbs every few months
-
Modern style = clean, updated look without overdoing it
2. LED Headlight Upgrade Options
Stock Acty Headlights:
Most Acty trucks (HA3/HA4) and vans (HH3/HH4) use sealed-beam halogen headlights with very limited output.
Upgrade Path:
-
Replace with H4 headlight housings (crystal or projector style)
-
Install plug-and-play H4 LED bulbs (ensure proper beam pattern)
-
Brands to consider: Sealight, Auxbeam, or Hikari for quality and fitment
Oiwa Tip: Avoid ultra-cheap LEDs with scattered beams—they can blind oncoming traffic and perform worse than stock.
3. LED Taillight & Brake Light Upgrades
Common issue: Dull brake lights or slow-reacting bulbs
Upgrade steps:
-
Replace 1157 dual-filament bulbs with red or white LED versions
-
Use CANbus-compatible LEDs to avoid hyperflash
-
Clean or replace old lens housings if faded or cracked
-
Add inline resistors if your indicators flash too quickly after the upgrade
Bonus: LED reverse lights make parking at night much safer.
4. Turn Signals, Side Markers & Dash Lights
These small bulbs are often overlooked but make a big difference.
Recommended LED swaps:
-
Front/rear turn signals: 1156/1157 amber LEDs
-
Side markers: T10 wedge bulbs (amber or clear with amber LED)
-
Dash cluster: T5 or T7 LEDs (blue, white, or red depending on preference)
-
License plate: 168/194 white LED
Hyperflash Fix:
-
Install LED-compatible flasher relay (available for most Acty models)
-
Or add load resistors to each turn signal circuit
5. Wiring Tips & Safety
-
Use dielectric grease on connectors to prevent corrosion
-
Clean grounds and check for brittle wires before upgrading
-
Consider fuse upgrades or adding an inline fuse for high-power LEDs
-
Use heat-shrink tubing and proper crimp connectors—not twist-and-tape
