Frequently Asked Questions

AI
Loom tape is a flexible fabric wrap used for bundling and protecting multiple wires, offering noise damping and abrasion resistance. Heat shrink tubing is applied individually to single wires or connectors to provide electrical insulation and environmental sealing, rather than cable management.
Yes, most high-power LED light bars require a relay to handle the current load directly from the battery, bypassing the vehicle's switch. This prevents overheating the switch and ensures consistent brightness. Check your light bar's amperage to confirm if a 40A or similar relay is included or needed.
Measure the diameter of the wire bundle you intend to wrap. The tape width should be wide enough to overlap slightly when wrapped around the bundle, ensuring full coverage. Common automotive widths range from 19mm to 25mm, suitable for most standard cable looms in cars and motorcycles.
