H4 headlight sockets were exactly as needed... February 18, 2018

Reviewer: Luckymann77

Great pair of ceramic pigtail wiring sockets.
Heavy duty adapter, just what I needed for a higher wattage than stock H4 bulb on my 2005 Vulcan 1600 Classic.

Heavy duty wiring sockets February 6, 2018

Reviewer: ahw

Used these ceramic wiring harness sockets to make relay change on H4 headlight. Cheaper than buying just sockets.

Great, cheap heavy duty ceramic harness sockets January 9, 2018

Reviewer: Jeffery V Williams

Cheap extension wiring sockets if you've converted to lenses and H4 bulbs with Rally Lights or Putco harness; gives ya an extra 4-5 inches to reach the driver light location without harness being taught against radiator and oil cooler ...I'd highly recommend these with the ceramic ports for the possible heat transfer to harness if you run anything about 55/60w bulbs. I melted a harness with rampage lenses and the Euro spec H4 Osrams at 80/100w. These can contend with the heat . On my 95 XJ , at least.

Much better than stock on my 2005 wrangler November 29, 2017

Reviewer: DR

These H4 ceramic harness sockets are very well built. Much better than the stock ones on my 2005 jeep wrangler. They installed easily after I cut one of the plugs off and spliced the wires. Highly recommend if your upgrading your headlights.

Works with 2002 Tacoma high watt bulbs July 27, 2017

Reviewer: bobby

I have a 2002 Toyota Tacoma, I put 80/100 Watts in with these ceramic harnesses and no other mods except 40 amp fuses to help supply . Never had any problems. First used 100/130 watt on high to see if any problems would surface. No additional relays needed so far. Just this one heavy duty ceramic wiring socket alone is enough
