    I have a 2013 Tundra that I haul a landscape trailer with. When I turn on my lights I don’t seem to get power to my trailer running lights. The brake lights work, turn signals work but no running lights. Any help would be very appreciated.

    Typically when I have had a trailer where some lights work but other do not, it has always been a bad/dirty connection- unless a bulb is bad. Clean the plugs/connections on the truck and trailer. Get them really clean, if you can see any dirt or crud it could be causing an issue. Give that a shot and see if it resolves the issue. While you are in there see if any of the pins or tabs are bent.

    Did you resolve this? I'm having a similar issue with my 2020. No running lights and no left turn.

    I had a bad towing fuse under the hood once that caused issue with trailers

    My issues have always been the trailer too.

    OP. Check where wires go into back of the light for bad connection. If it's one upstream nothing behind it will work either. At least on mine.
    Sometimes I have to rotate the bulb just right to get brake lights and running lights to work correctly. At the back of the bulb are two bumps and those need to sit right on the metal tabs in the light housing.

    My problem was the 30amp fuse underhood and whoever wired my trailers 7 pin connector was color blind/couldn't read.
