HIRCQOO 1/10 RC Crawler LED Headlights - 18mm & 20mm White LED Lamps for TRX-4, SCX10, Redcat Gen8

These HIRCQOO LED headlights are built for 1/10 scale RC crawlers and trail trucks, including popular models like the Traxxas TRX-4, TRX-6, Axial SCX10 II 90046/90048, Redcat Gen8, RC4WD D90/D110, and CC01. The set contains two different housing sizes—18mm and 20mm—so you can match the bumper holes on your specific rig. Each housing holds a 5mm white LED that runs on 5–7V DC, drawing power from your receiver or ESC via a standard JST/JR connector. Installation is straightforward: plug into an open channel on the receiver, or use a JST Y-harness (not included) if connecting to the ESC. The metal and plastic construction feels solid, and the wire length of 400mm gives you enough slack to route neatly inside the chassis. Whether you're running night trails or just want a more realistic look, these lights add visibility and scale detail without draining your battery.

Compatibility Across Popular 1/10 Scale Crawlers

• Traxxas TRX-4, TRX-6
• Axial SCX10 II (90046, 90048), SCX10 (earlier versions)
• Redcat Gen8
• RC4WD D90, D110
• CC01, KM2
• Most 1/10 scale climbing cars with standard 18mm or 20mm mounting holes

Two Housing Sizes for a Better Fit

The 18mm housings measure 18 x 13.2mm and the 20mm housings measure 20 x 14mm. This means you can choose the size that fits your bumper cutouts exactly. If your truck uses the smaller diameter, use the 18mm set; for larger holes, the 20mm set sits snug. Both use the same 5mm LED and wiring, so swapping is simple.

Power and Wiring Details

These lights work on 5V to 7V input, which covers the typical voltage from a receiver (around 5–6V) or a 2S LiPo through an ESC (7.4V nominal). The connector is a standard JST/JR male plug. To power them via the ESC, you will need a JST Y-harness cable (sold separately). The 400mm wire length gives enough reach to run from the front bumper to the receiver or ESC tray on most 1/10 chassis.

Common Questions About These RC Headlights

Are these plug-and-play with my TRX-4?
Yes. The JST/JR connector plugs directly into the receiver's channel 1 or channel 2 slot. If your receiver uses a different plug style, you may need an adapter.

Can I run these lights from the ESC without a receiver?
You can connect them to the ESC's BEC output using a JST Y-harness. Just ensure the voltage is between 5 and 7 volts.

Do these headlights have an on/off switch?
No, they are always on when powered. To turn them off, unplug the connector or install an inline switch (not included).

Will the 20mm housings fit in 18mm bumper holes?
No, the 20mm housing is larger. Use the 18mm set for smaller holes and the 20mm set for larger openings.
