The Morimoto LF371 XB LED fog-light pair replaces the matching original fog lights on 1999–2016 Ford F-250 and F-350 Super Duty trucks. The projector housings produce 5500K white light and use an H10 input. The 1999–2010 application requires minor modification; check the mounting before installation.

Before installation
Check the installed fog-light mounting and connection before disassembly. On 1999–2010 trucks, review the required minor modification with the installer before fitting the lamps. Use the integrated height adjuster to aim the fog lights after installation; an electrical connector match does not establish correct mounting or beam aim.

Product questions and answers
Does LF371 fit both early and later Super Duty trucks?
The listed range is 1999–2016 F-250 and F-350 Super Duty. Morimoto separates 1999–2010 trucks, which require minor modification, from the 2011–2016 application. Check the original fog-light equipment as well as the year.
Are the 1,200 lumens per lamp or per pair?
Morimoto rates each LF371 lamp at 1,200 raw lumens, or 2,400 raw lumens for the pair. Raw lumen output is not a measurement of light reaching a particular point on the road.
Is this an H10 replacement bulb set?
No. LF371 includes two complete LED projector fog-light assemblies. H10 describes the electrical input; the set replaces the matching lamp housings rather than only the bulbs.
Can I install these without aiming them?
The housings have an integrated height adjuster. Check and set the fog-light aim after mounting; a lamp can connect electrically and still need adjustment.
Are yellow fog lights included?
The base LF371 lamps emit 5500K white light. Yellow Lamin-X film is listed as an optional accessory, so do not assume it is included in the standard pair.
What should I compare if my truck has a replacement bumper?
Compare the lamp shape, mounting points, available clearance and H10 connection with the installed bumper. A replacement bumper can use different fog-light equipment from the original truck.
What warranty applies to this pair?
The product carries Morimoto's 10-year limited warranty. Manufacturer terms, exclusions and the original proof of purchase apply; the warranty does not make an incorrect application compatible.
