Question:

Hi I love these lights and I put them on my 1964 trailer. However, I would like the tail lights to be a bit brighter. Can I use a brighter bulb? Can I use a LED? Thanks for your advice.

Hi Tami,

Great question! You can definitely replace the bulb in your Optronics tail light, part # ST90RB, with a brighter option. The bulb that's currently in your light is a standard 1157. You can swap that out for an LED, like part # ARC63FR.

LEDs are a great upgrade they last a lot longer, and these particular LEDs put out a bright 600 lumens, so you’ll get a noticeable improvement.

1964 is an older trailer! Just out of curiosity, what kind of trailer is it?
