LightWorks Labs Wiring with Inverter for Lyft and Uber Glow Signs and Lights Wiring assembly for LightWorks Labs illuminated glow signs and most EL (electroluminescent) lights Extra-long cable length allows you to run your wires behind dashboard or underneath carpets for concealment and a professional-looking installation Simply plug and go with the modular jacks (jacks are polarized, and will only plug in when aligned with the proper polarity) Small, easy-to-conceal inverter transforms your car's 12 volt current to the required voltage for EL signs Minimal amperage draw: less than 1 Amp for a 4" x 6" sign
