Trailer lights are important when it comes to safety on the road. Without them, other drivers won’t be able to see you and you could easily be involved in an accident. That’s why it’s important to ensure they’re working properly and, if they stop working, to get them fixed before hitting the road. So why is my trailer lights not working?
There can be a few causes for this issue, although they tend to stem from either a wiring problem or a fault with the bulbs themselves. To identify the source of the issue, look for any visible damage or corrosion on the wiring or bulbs. If noticed, it’s best to replace the entire assembly rather than try to patch individual components together.
If no physical damage is present, then a more thorough inspection is needed. Disconnect all connections and use a multi-meter to test each one, looking for any voltage drops or shorts. Oxidation can also be a factor, so clean any contacts as well. If everything checks out, replacing the bulbs may be the only option. Alternatively, buying LED headlights greatly reduces the need to replace bulbs since they’re much more efficient and long-lasting.
In conclusion, if your trailer lights are not working, then it’s likely caused by a wiring issue or a faulty bulb. To check, inspect the wiring and clean any contacts, then test them with a multi-meter. Replace the entire assembly if there’s physical damage, and try swapping out the bulbs for LED versions, which are much more reliable.
