Features & benefits
-
Compact form factor: At roughly half the size of our full‑size 9005 PWM module, this decoder fits inside the smallest headlamp housings without drilling or modifying dust covers. It is ideal for Peterbilt 389/567/589 trucks as well as cars and SUVs with tight space behind the headlight.
-
Wide compatibility: Supports 9005 (HB3), 9006 (HB4) and 9012 (HIR2) bulb bases (and compatible variants like 9005A/H10/9145). Works with LED headlights, fog lights or DRLs. Not recommended for HID ballasts that exceed 4 A draw.
-
Stable power & reduced noise: The upgraded resistor‑capacitor design eliminates flicker, solves radio‑frequency interference, and prevents the lights from shutting off when the engine starts. The aluminum heat‑sink housing provides adequate dissipation despite the smaller size.
-
Quality construction: Weather‑sealed connectors with silicone gaskets ensure durability in harsh environments. The module is rated IP65 and can be mounted using the included double‑sided tape or zip ties.
-
Plug‑and‑play: Clearly marked positive (+) and negative (–) leads simplify installation. Simply disconnect your factory plug, insert the decoder in‑line, and reconnect your bulb. No cutting or splicing required.
Fitment and compatibility
This compact decoder is suitable for most vehicles using 9005, 9006, 9012 or 9145/H10 bulb bases, including heavy‑duty trucks, passenger cars and motorcycles. It is particularly helpful for vehicles that:
-
Use a CAN‑Bus electrical system and display bulb‑out warnings when LED bulbs are installed.
-
Use pulse‑width‑modulation (PWM) DRLs, causing LEDs to flicker or dim.
-
Have tight headlamp housings where full‑size decoders cannot fit, such as Peterbilt 389, 567 & 589 trucks.
If your vehicle does not have a CAN‑Bus system or you are not experiencing bulb‑out errors, a decoder may not be necessary. For vehicles drawing more than 4 A per bulb or requiring a higher load, our full‑size 9005 PWM module may be more appropriate.
