Symptoms of a Failing Headlight Switch
When a headlight switch starts to go bad, it can cause several noticeable problems. Being aware of these signs can help you figure out the issue before you're left in the dark.
- Lights Don't Turn On: The most obvious sign is when your headlights or parking lights won't turn on at all. You might also find that only one setting works, like the high beams, but the low beams do not.
- Flickering or Intermittent Lights: If your headlights or dash lights flicker, dim, or cut out while you're driving, the switch's internal parts are likely worn. This can be more noticeable on bumpy roads.
- Dimmer for Dash Lights Fails: The part of the switch that controls the dashboard light brightness can fail. You might find the dash lights are stuck on one brightness or don't work at all.
- Switch Feels Hot: If the headlight switch knob or the dash around it feels warm, it's a sign that the switch is overheating due to high electrical resistance. This can be a fire hazard.
- Headlights Won't Switch Off: In some cases, a faulty switch or related component can cause the headlights to stay on even when you turn them off, which will drain your battery. 🎬 Watch this video if your headlights won't turn off.
Pro Tip: Before you replace the switch, always check your fuses first. A blown 20-amp fuse (often in position #10 in the fuse box) can cause symptoms that seem like a bad switch. If you replace the switch and the lights still don't work, a blown fuse is the likely reason.

For a vehicle like the 1987-1991 E-150, you don't need to buy an expensive part from the dealer. Aftermarket parts offer good quality and value. Here’s a look at the brands available:
- Standard Ignition (Standard Motor Products): This is a well-regarded aftermarket brand known for making quality electrical parts that meet or exceed original specifications. Many professional mechanics and experienced DIYers trust this brand for its reliability.
- Rostra Powertrain: Rostra is a US-based manufacturer with a strong reputation for quality electronic components, including switches. They are an ISO-certified company, which means their parts are made to a high standard of quality.
- Replacement: This is a generic or store brand. These switches are the most affordable option and can be a good choice if budget is your main concern. They are designed to fit and function like the original part but may not have the same long-term durability as premium aftermarket brands.
For a critical part like a headlight switch, choosing a reputable brand like Standard Ignition or Rostra is a smart investment in reliability. However, a basic "Replacement" brand switch will also get the job done.
| Brand Tier | Estimated Price |
|---|---|
| Premium Aftermarket (Standard, Rostra) | $45 - $78 |
| Value/Economy (Replacement) | $25 - $44 |
Frequently Asked Questions (FAQ)
Is it hard to replace the headlight switch on a 1987-1991 E-150?
No, it is a fairly simple job for a DIYer. It involves removing the dash trim panel around the switch, unscrewing a retaining nut, unplugging the electrical connector, and swapping the part. The main challenge is reaching a small release button on the switch body to remove the pull-knob and shaft.

You will need basic hand tools like a socket set or Torx drivers to remove the dash panel screws. A pair of pliers can be used to unscrew the retaining nut that holds the switch to the dash. A trim removal tool can also be helpful to avoid scratching the plastic dash panels.
Are there any recalls for this part?
No specific recalls were found for the headlight switch on the 1987-1991 Ford E-150 Econoline. Later model Fords had recalls related to a Lighting Control Module, but this does not apply to this generation of Econoline vans.
My lights still don't work after replacing the switch. What's wrong?
First, check the fuse for the lighting circuit (often a 20-amp fuse in slot #10). It's common to blow this fuse during installation if the battery is not disconnected. Also, check the electrical connector for any signs of melting or corrosion. If the connector is damaged, it will also need to be replaced.
