What year is the truck? Probably either switch will work fine, but hopefully someone else will know what the difference really is.

I have never seen where a serial # of a truck matters on the headlight switch. So when you went to the parts store they asked you the truck serial #?
Something I found....
Sample VIN: F10AU100001
First three characters - F10 - Truck Series Code
F10 - F100 2 Wheel Drive
F11 - F100 4 Wheel Drive
F14 - F150 4 Wheel Drive
F15 - F150 2 Wheel Drive
F25 - F250 2 Wheel Drive
F26 - F250 4 Wheel Drive
Fourth character - A - Engine Code
A - 6 cyl - 240cid - 1BBL carb - 1973-74
B - 6 cyl - 300 cid - 1BBL carb - 1973-80
G - V8 - 302cid - 2BBL carb - 1973-80
H - V8 - 351cid - 2BBL carb - 1973-80
Y - V8 - 360cid - 2BBL carb - 1973-76
H - V8 - 390cid - 2BBL carb - 1973-76
M - V8 - 390cid - 4BBL carb - 1974-78
S - V8 - 400cid - 2BBL carb - 1977-80
J - V8 - 460cid - 4BBL carb - 1973-80
Fifth character - U - Assembly Plant Code
B - Oakville, Ontario, Canada
C - Ontario, Canada
E - Mahhaw, NJ
H - Lorain, OH
I - Highland Park, MI
K - Kansas City, MO
L - Michigan Truck
N - Norfold, VA
P - Twin Cities, MN
R - San Jose, CA
S - Allen Park, MI
U - Louisville, KY
V - Kentucky Truck
Remaining six characters - 100001 - This is a numeric code for the vehicle build sequence. In some cases there could be two letters and four numbers.

To get a walk thru on how to remove the headlight switch stud and **** to get the dash bezel off to get to the switch go here. And welcome to FTE. You do not have to remove your instrument cluster just the bash bezel.

^ Y'all may never have seen a headlamp switch that the VIN is required to get the correct one, but it does matter in this case since the OP has a 1976.

What is the difference between serial number before 25000 or from 25000?
Serial number is the last 6 digits of the VIN

1967/77 begin with a letter followed by 5 numbers. 1978/80 begin with two letters, followed by 4 numbers.

D3ZZ-11654-A (replaced C5DZ-11654-A; C5TZ-11654-A, B & C; C5ZZ-11654-A; C8UZ-11654-A; D1ZZ-11654-A and etc.) .. Headlamp Switch KIT (Motorcraft SW-1245)

1965 Falcon / 1965/66 Mustang / 1965/66 F100/1100 / 1967/72 F100/750 / 1969/75 Econoline / 1971/72 Mustang/Cougar // 1973/75 F100/350.

1976 F100/350 & Econoline before serial number C25,000.
------------------------------------------------------------------
D7TZ-11654-A .. Headlamp Switch (Motorcraft SW-1381) / Marked: D7TB-11654-AA

1976 F100/350 & Econoline from serial number C25,000 / 1977 F100/350 & Econoline.
