At Aspire Auto Accessories we carry our own high temperature connectors that can withstand high temperatures and prevents melting. Manufactures equip vehicles with plastic versions of headlights plugs which are prone to melting over periods of time or due to excessive use at night. We offer the best quality connectors, with competitive pricing and free shipping on all headlight connectors and replacement pigtails. We have these connectors readily available and our manufacturing capabilities allow you to build your connector exactly how you want unlike most sellers.

Choose from 14 Gauge or 12 Gauge Headlight Wires - Our wire is USA made. Don't settle for import wire! Import wire typically has extra thick insulation that makes the copper "under gauge"! Additionally, most import wire we see has very poor quality copper.

Step 1: Select Wire Length

  • Unassembled - Terminals and Seals ONLY (Included) - When selecting this option you receive no wire with your purchase and must source your own.
  • 6 Inches (+$1.00) - Our standard wire length
  • 12 Inches (+$2.00) - Upgrade and extend your wire length of the connector
  • 24 Inches (+$3.00) - Upgrade and extend your wire length of the connector
  • 36 Inches (+$4.00) - Upgrade and extend your wire length of the connector

Step 2: Select Power Wire Gauge

  • 14 Gauge (Included) - Our standard wire gauge
  • 12 Gauge (+$5.00) - Upgrade your wires that goes to the headlight bulb and factory harness to thicker wire.

Step 3: Soldered Connections

  • No (Included)
  • Yes (+$1.50 per wire) - Have us solder your machine crimped connections so you can have the most secure & reliable harness. Solder is NOT common in vehicles, but is routine in aircraft because it produces the best union of wire to terminal.
