Highly recommend these fog light harnesses May 9, 2018

Reviewer: Jesse Ortega

I give 5 stars because since I used this heavy duty ceramic socket set it was the end of my nightmare. The original HB3 socket melted. I replaced it with another another oem socket and few months later same issue until I used iJDMTOY

QUALITY and heat-resistant harness April 24, 2018

Reviewer: Roy Bradrick

Get CERAMIC connectors to replace your old, melted, or corroded HB4 plastic headlight harnesses.  For whatever reason I went through several OEM and aftermarket plastic connectors - they melted and screwed up the headlight contacts as well.  This heavy duty ceramic harness socket set is robust and has survived.

Ceramic Sockets+Thicker Wires = Less Heat April 1, 2018

Reviewer: kuyaKC

Fit perfectly. Purchased as insurance for converting my low beams from H11 to the higher wattage H9 halogen bulbs. Modified the H9 bulb female connector to accept the H11/H8 harness. Be careful not to force the plug into the socket- the ceramic does give a ?€?crunch?€? as the metal prongs slide into the ceramic insulator, but you?€?d be fine as long as it?€?s going in straight. Well made product.

Good Stuff Maynard ! March 11, 2018

Reviewer: D.B. Kracker

These H4 ceramic harness sockets were a nice upgrade from factory plastic connector blocks. I knew there was a connector issue on old blocks but had no idea how bad until removing old melted connectors and realized the need to cut off the male ends of the new replacements and butt splice them direct into wiring harness. The heavy duty socket wires were heavier gauge than the stock harness (99 Honda CRV). Overall very happy with parts and should have bought the ceramic connectors without the plug and play male end, who knew?? As an old school auto service guy having the tools and supplies, it was still a good buy and a recommended buy, also bought the Phillips +30% headlamp bulbs because I did not want a really hot burning hyper-white to overheat connectors again.
