Weak/ Dim rear lights

  1. Hi All,

    I have a 1976 ex Florida bus and I have some questions about the rear lights.

    I got a message after leaving a friends last night to tell me I had not rear lights going home.

    So went out to check this morning and they indded were not working. I assumed it was a poor connection, dirty etc so removed the lenses and the bulbs and cleaned everything a bit.

    The bulbs were sitting in the holder and not "clipped in" using the little notches on the side of the bulbs which I found strange.

    When I pushed them in like this the lights shone brightly, but when I twisted them in the "fastened" position they were really dim.

    So in the correctly fitted position I have strong brake lights but very dim night lights.

    OR I can have them resting in position (they will come loose after driving) and I will have stronger night lights but very weak brake lights.

    Has anyone else come across this, could it be European bulbs on a US bus? Do I need to change the connector plate behind the bulbs??

    I am going to check the strength again tonight when it is dark and take some pics to show how dim the lights are and will of course post here.

    Anyone with a similar problem??

    the bulbs are the same, it's possibly just crappy aftermarket connectors they don't seem to line up right, clearly the bulbs/volts is right so you've answered the question......

    Sometimes the solder pip that makes the bulb connection melts away making a Poor connection
     
  4. Yes I just redid my rear lights but the bulbs weren't making good contact and I had to refit the original backing plates.
     
  5. Does the bulb holder have two contacts inside for european brake/sidelight bulbs? Or just one?
     
  6. It only has one.

    OK so after my clean up around the contacts I just went out in the dark and put my lights on...they shine bright like a diamond (but red) so all my questions are solved.

    They just looked really weak in the daylight, the brake light is 10X brighter than a normal rear light so thats why I thought there was a problem!
