How to find the right Automotive Combo Parking & Side Marker Light Assemblies AI guide

What the AI looks for in Automotive Combo Parking & Side Marker Light Assemblies

Bulb base
Most use a dual-filament bulb (commonly 3157/3457 or 1157 on older vehicles); match the socket to your existing harness The dual filament runs parking (dim) and turn (bright) from one bulb, so the socket type determines whether the lamp works at all.
Lens type
Amber lens with a clear bulb, or clear lens with an amber bulb; keep the same setup as the original A clear lens with a white bulb puts out the wrong color and is not legal for the front marker.
Fitment by grille and headlamp style
Match single versus dual headlamp, composite versus sealed-beam front ends on older trucks Parking and marker combos on pickups and vans change shape with the headlamp package of the same model year.
Socket and harness
Replace a corroded or heat-browned socket at the same time; check if one is included Melted or corroded sockets cause flicker and dim output even with a new housing.

Brands that matter

  • Depo: OE-style replacements, also under the Maxzone brand.
  • Eagle Eyes: Common for domestic pickups and SUVs.

What to avoid

  • Clear or smoked styling lenses run with white bulbs on the street
  • Plug-in LED bulbs in these housings without checking hyperflash on the turn function
