To begin with, these are by no means "plug and play". If you want "plug and play" buy other lights. If you don't mind working on a brand new product to make it work right and you have some basic skills it can be done. There are several issues that need to be fixed. First is the turn signal plug. The stock turn signal bulb in my 2011 accord sedan is a 1157, not a 3157. So the blade plug wired to these lights will not work and needs to be removed and replaced with something else. I used the blade connectors shown in the pic. There are three wires on the stock harness, you can use a voltmeter to find the correct wire that runs the turn signal. Since the 1157 socket is much larger than the 3157 blade type the hole provided in the housing is too small for the 1157 socket to plug, you'll have to plug the hole with something. I found an un-used plug from another project shown in the pic with the connectors. Second, the plugs provided for the low beam bulb only work for H7 bulbs. There is no way to use the other type of bulbs listed. H7 LED will not fit inside the hole in the reflector so the only option is H7 halogen. On top of that the bulb doesn't fit inside the socket and I had to rig it inside the mounting collar by shaving about .02" from the inside radius with a round file so it would fit the way it does in the pic. I'm not sure it's supposed to go in that way but that's what I did to make it fit because I couldn't get it to go in any other way. I tried to fit the other bulbs suggested and they would not fit in any way. The third issue is the cord provided for the driving lights/halo. In the instruction diagram it's shown to be plugged into the under hood fuse box, however there is no circuit in that box that isn't constantly powered so if you use any of them your halos will be on constantly even with the key off. The wire has to be lengthened so that it can reach the fuse block at the driver side kick panel. Routing the wire there takes some work. I found #1 to be an open accessory to plug into. The fourth issue I found was the rubber cover on the high beam plug. It's loose and likely would fall open. This is easily fixed with a long zip tie. The final issue is the adjustor motor. My car has no adjustor motors, or wiring for them, so it's a non-issue extra part unless you're like me and want everything to work if you can make it. I found out these motors come from a 2011 Honda Odyssey and I ordered some 3 pin connectors so that in the future I can wire them up to a switch and see how they work. Until then I'll use the manual adjustment. After all that they seem to fit and function well and look sweet. The sequential turn signals are awesome and the main reason I put in the work to get these to function properly. I hope all this work proves to be worth it and they last a long time. I may try to convert the low beam sometime so that I can use an LED. If I do I'll update this review with information on how.UPDATEI bought these LEDs and they work great. They fit properly, unlike the h7 bulbs I had rigged in place, and they're bright. To install them remove the metal mounting ring from the bulbs put it through the plastic ring and re-attach the metal ring and plug in the wires. I was careful to try to get the wires away from the ballast/fan hoping they won't melt. It's easier to get them lined up with the little tab on the plastic ring and then put them in while holding the back of the bulb (like the pic) so it's in position then put the ring on.https://www.amazon.com/dp/B08J75SCHN/ref=cm_sw_r_cp_apa_i_nHN-FbHH1HBMJ?_encoding=UTF8&psc=1these headlights look great. however, they’re not 100% “plug and play”. Everything is plug and play until you get to the turn signal harness. i had to cut the harness off (so there was nothing left but wires) and i had to actually wire the factory harness and aftermarket headlights together. just a warning, but when you get past that these headlights looks amazing!I purchased these on March 19, 2020 & did not get to install them until today.. 11-30-20 due to various reasons. The turn signal on my 2010 Accord 4 door is an 1157 bulb & the assembly requires a 3157 bulb. Therefore they WILL NOT wire up correctly! No way to adapt them so the socket fits with a good seal on the turn signal socket. I even emailed the seller on February 29th for verification & they told me these are basically plug & play. Now I’m stuck with these & no car until I get another set. Very disappointed here!!!this is my 3 rd set of headlights .....I happy to say that these work great on my 08 accord exl sedan ..I def recommend you spend the money on theseThey seem to be a great build quality, loved them while I had themOnly one wire harness matches the car the rest do not. There’s no adapters and this set up requires that you plug a fuse harness into the fuse box which does not fit anywhere inside the box. Very upset since you don’t know this until you’ve disassembled the front end!Fits great and looks goodHow come my headlights not working in my car?
