The Cave, Lighbulbs page at the had bottom about DOT code meaning and NHTSA links to "Posters" for External Lights etc but Link are dead as NHTSA moved or updated the posters. (Before you ask... Cave is Read Only and even I can't edit pages.)

You can find copies of both "posters" using web search but even they don't have all code for whatever light fixture.

I recently found a older version of SAE-J759 (publish 1995) and most valid codes that even covers aftermarket "DOT Approved" taillight and other fixtures... @ https://law.resource.org/pu...5/sae.j759.1995.html
Code List:
code:
TABLE 1—LETTERS INDICATING DEVICE FUNCTIONS 
A Reflex reflectors
A2 Wide angle reflex reflectors
C Motorcycle auxilliary front lamps
D Motorcycle and motor-driven cycle turn signal lamps
E Side turn signal lamps—vehicles 12m or more in length
E2 Side turn signal lamps—vehicles less than 12m in length
F Front fog lamps
F2 Fog tail lamps
G Truck cargo lamp
H Sealed beam headlamp
HG Discharge forward lighting (headlamp)
HH Sealed beam headlamp housing
HR Replaceable bulb headlamp
I Turn signal lamps
13 Turn signal lamps spaced from 75 mm to less than 100 mm from headlamp

16 Rear mounted turn signal lamps and front mounted turn signal lamps mounted 100 mm or more from the headlamp, for use on vehicles 2032 mm or more in overall width
17 Front mounted turn signal lamps mounted less than 100 mm from the headlamp, for use on vehicles 2032 mm or more in overall width
J590 Turn signal flasher
J945 Hazard warning signal flasher
J1054 Warning lamp alternating flasher
K Front cornering lamps
K2 Rear cornering lamps
L License plate lamps
M Motorcycle and motor-driven cycle headlamps—motorcycle type
N Motorcycle and motor-driven cycle headlamps—motor driven cycle type
O Spot lamps
P Parking lamps
P2 Clearance, sidemarker, and identification lamps
P3 Clearance, sidemarker, and identification lamps for use on vehicles 2032 mm or more in overall width

QC Vehicular hazard warning signal operating unit
R Backup lamps
S Stop lamps
S2 Stop lamp for use on vehicles 2032 mm or more in overall width
T Tail lamps (rear position lamps)
T2 Tail lamps (rear position lamps) for use on vehicles 2032 mm or more in overall width
U Supplemental high-mounted stop and turn signal lamps
U2 High-mounted stop lamps for trucks 2032 mm or more in overall width
U3 Center high-mounted stop lamp for passenger cars, light trucks, and MPVs
W Warning lamps for emergency, maintenance, and service vehicles
W2 Warning lamps for school buses
W3 360 degree emergency warning lamps
W4 Emergency warning device
W5-1 360 degree gaseous discharge lamp—Class 1
W5-2 360 degree gaseous discharge lamp—Class 2
W5-3 360 degree gaseous discharge lamp—Class 3
Y Driving lamps
Y2 Daytime running lamps
Z Auxiliary low beam lamps


Note: 13 14 15 16 17 maybe I3 I4 I5 I6 I7. Is copied from the link that may has wrong auto spell etc.
Example: The Trunk Poster only list U3 for High Brake but other versions of High Brake are labeled as U or U2 depending on different design, size of vehicle, etc. Like in https://www.fiero.nl/forum/...HTML/146359.html#p12 Cyclopes Lens is labeled DOT/SAE U84 CYCLOPS where U is High Brake, 84 year to meet FMVSS, Cyclops for ID who made. (also said Patented but not legal to have that.)

Oddly OE Fiero High Brake lens, likely because of size, has DOT 86 on left side and Guide on right and is missing U3. Haven't taken apart this fixture in years to look other marking like used for side markers like shown in the cave.

NOTES:
Also including Flasher Numbers that's often printed on them...
code:
J590 	Turn signal flasher
J945 Hazard warning signal flasher
J1054 Warning lamp alternating flasher


You should not see them labeled on lenses.
W codes are for Flashing Lights, Light Bars, etc, for School Buses, First Responders, Tow Trucks and such. You won't see them on normal taillights...
I think 13 and others are typos and should be I3 etc
This is Missing HB2 and some other newer Headlight codes.

Currently NHTSA has the "Posters" here & maybe added newer codes. Not checking every entry.
