I would like to upgrade my trailer to LED bulbs.  Can anybody recommend a good buld and/or source?  I have 21 bulbs in the trailer so I will do it a few at a time.

 

Thanks for the recommendations.

Thanks War Eagle, you have given good advice.

How do you know that the LEDs are voltage regulated?   Does this only apply to replacement lamps or are DOT approved units voltage regulated?  Or are the sellers just guessing you'll not use the trailers enough to have the lights fail or won't bother to return if they do?

It has been my experience that if they are not voltage regulated then the vendor doesn't advertise that and they post voltage requirement as simply 12v.

 

Vendors that offer voltage regulated lamps will post voltage requirements as 5-30v, or 7-14v etc., or some will simply post it it the technical info section as specific feature for their lamps.

 

You can buy cheaper LEDs on ebay but they will not last.  Look for the voltage regulation feature.
