These are a good quality and were a perfect fit for my 2011 Nissan Titan. Came with high beam and low beam as advertised, not the side marker bulb or the blinker bulb.Something I did notice before I purchased was the 2011 Titan has Amber shaded blinker and side marker lights on the assembly, this one is all clear. So, you won't be able to use the current bulbs if you also have an amber shaded lens, otherwise your blinker and side marker will be bright white also. I just ordered some led replacements for both in an amber color. Another note, if you purchase a 3156/3157 led replacement for your turn signals, make sure to get one with a built in resistor or you will have "hyperflash" where your turn signals will flash faster than normal and may get an error in your instrument panel advising that you have a burnt out bulb. Or you can just order the old style 3157 in an amber color and not worry about hyperflash.Also, know that on my 2011 anyway, there is a piece of trim that attaches to the bottom of the headlight assembly. You will need to remove that trim and add to the new assembly. I recommend searching youtube on changing the headlights out so you can see how that trim detaches. It has those plastic grommets that look like all the others and you think you can just squeeze them and pull them out, but actually all you have to do is slide them both to the side at the same time, which is rather easy. Mine didn't attach to the new assembly tight enough to stay in place, probably worn out. You may want to get some new ones before installing. I didn't, but I didn't really care about future changes as I don't see myself changing these assemblies again in the future, so I just hot glued them in place. If I do have to replace them, I will just have to dig the hot glue out from around the inside of the grommets.Another lesson learned for me, before putting it all back together, test your lights after plugging them in. The plugs will allow you to inserts the wires in both directions. One being right and the other being wrong. When I tested my driver's side, the high beam wasn't working. I played with the connection, unhooked and rehooked it up and it started working, so I thought I just had a bad connection. When I went to install the passenger side, neither the high or low beam was working. That is when I realized I inserted the plugs upside-down. When I flipped them over, both worked.End result, both are working great. Nice and bright and has a nice clean and crisp appearance. No gaps between the assembly and trim or grill. Everything bolted up using existing equipment and holes/grooves/et cetera thout having to drill or relocate anything. Looks like the old ones did, only new and cleaner.
