Sure thing. Below is the amazon link for the LEDs. ~$12. Simple rocker switch was a couple bucks and I had the wire and heat shrink in my junk drawer. So maybe $20-25 total if you had to buy everything. The LEDs have a 3M type backing tape and you can cut them every few inches and solder leads to them. I heat shrinked each cut connection to keep them “water resistant.” I have a Bakflip MX4 so I ran one strip from side to side on the bottom of the fixed front of the cover and one strip down each silver rail. Takes some soldering skills and hopefully the LEDs last but if not... it was $15
