Review on 🔌 H4 LED Headlight Wiring Harness Kit - Negative Switched Conversion - Fused - for 9003 H6054 H5054 H6054LL 6014 6052 6053 - Suitable for Subaru Toyota Head Lights by Daniel Mind

So this works great on my Datsun. Used with 5.75" Harley Davidson headlights with high/low capability. But! But the relays are very noisy when turning on and off. And perhaps most alarmingly, the wiring for the power supply is 14 gauge (maybe even 16 Gauge) ) wiring disguised as 12 gauge.I discovered this because I wanted to use a waterproof fuse holder instead of the fuse holder provided. Seriously! I replaced the inadequate wiring but to do this I had to remove power to the relay. 3 stars, because it works for what i need just give it some extra attention and materials.
