Default Trunk Lights Dim

Hi, so yesterday I tried to connect a LED strip to my truck light located inside the trunk in the center, After connecting and not getting the strip to light up, I noticed now the other truck light on the actual trunk lid is dim and measuring about 4.5 volts (previously 12 volts) I checked the 7.5 A fuse 3 (RR ECU-B) in the truck fuse box and it was not blown. Taking out the fuse turns off the trunk lights, inserting it back turn it on but at a lower voltage. Is it possible the LED strip damaged a control module without blowing the fuse? Any help would be appreciated as I am stuck at this point. Thanks!

Thanks for the reply but my title may have been misleading. I have an electrical problem with my trunk light voltage and am looking to help root cause it.
