I bought this with the intention of adding visibility. It does that, but I knew the halogen 1157 wasn't going to be bright enough. I bought this LED to replace it, which was the best I could find for the price:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/JDM-ASTAR-Super-Bright-5730-Chipsets-1157-2057-2357-7528-LED-Bulbs-with-Projector-Brilliant-Red-2yr-Warranty-Included/dp/B00WW28T16/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">JDM ASTAR Super Bright 5730 Chipsets 1157 2057 2357 7528 LED Bulbs with Projector,Brilliant Red--2yr Warranty Included</a>. I also wanted to make sure my $10 LED bulb didn't get stolen, so I bought this hitch lock:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Trimax-T-3BLACK-Premium-5-8-34-Key-Receiver-Lock-Rugged-BLACK-epoxy-powder-coat/dp/B000W0RQ8C/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Trimax T-3BLACK Premium 5/8" Key Receiver Lock Rugged BLACK epoxy powder coat</a>. I also needed a power adapter to fit my truck:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Hopkins-47345-4-Wire-Flat-Adapter/dp/B0002RNSKK/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Hopkins 47345 4 Wire Flat Adapter</a>. Then I wanted to ensure it couldn't get any brighter and bought some red reflective tape to cover the insides of this:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Heskins-REF2R-Red-Reflective-Tape-2-34-x-10-yd/dp/B003EMZ24A/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Heskins REF2R Red Reflective Tape, 2" x 10 yd</a>. This was kind of a hassle and maybe red reflective paint would've been easier, but less effective.
