I pulled the white out of the top and crimped an extension wire on. The carpet on the shelf was glued down well, so I ended up using a paint scraper to lift the carpet to get to the wires. I crimped on a marine grade heatshrink butt connector to extend the wire. It&#8217;s overkill for a trailer &#8212; the shelf is unlikely to be doused in saltwater &#8211;, but it&#8217;s the parts I had on hand. I didn&#8217;t have a matching white so I used the black I had and put white tape on the wire coming down through the hole.  The light uses marine colors, red for positive and black for negative \/ ground, while the trailer uses residential black for positive and white for negative \/ ground. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-1024x768.jpeg?resize=1024%2C768&#038;ssl=1\" alt=\"Round and square lights under side cabinets.\" class=\"wp-image-643\" srcset=\"https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-scaled.jpeg?resize=1024%2C768&amp;ssl=1 1024w, https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-scaled.jpeg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-scaled.jpeg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-scaled.jpeg?resize=1536%2C1152&amp;ssl=1 1536w, https:\/\/i0.wp.com\/gerardweatherby.org\/camping\/wp-content\/uploads\/2026\/04\/roundlight-8-scaled.jpeg?resize=2048%2C1536&amp;ssl=1 2048w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><figcaption class=\"wp-element-caption\">New and old<\/figcaption><\/figure>\n\n\n\n<p>The lights don&#8217;t match, but I expect the switches will last much longer than the stock RV-style ones.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The interior lights that come with the Casita are &#8230; affordable.
