The install was simple and straight forward. The look just adds to the ST front end. Anyone looking for a better look over the stock headlight, this is it!
Looks great on my Lowrider ST. It has an aggressive look to it and changes up the overall look of the bike/profile of the fairing. Adjustability is limited as far as the height of the beam goes. It is maxed out in the up position and that puts it almost to where it should be as far as adjustment. Overall it's a great product.
I was underwhelmed by the stock headlight on my Low Rider ST and looked at several competitors before choosing the Shark Demon®. My main requirements were a DOT-compliant light that provided excellent output without blinding other drivers, a clean and aggressive aesthetic, and a design that required no modification to the fairing.
This headlight delivered on all counts. As someone who is 54 and rides frequently at night in the SF Bay Area—often traveling 30 to 90 miles for local meetups—having reliable, high-quality lighting is essential. With my prescription glasses, the visibility improvement is fantastic. This is a top-tier upgrade that balances performance and ease of installation perfectly. Highly recommend.
I have the signal lights, glad I went with them for the headlight. I was undecided between Moons & Baja. I didn’t need to see like a fly or send a bat signal in the desert. I needed a headlight with top of the line quality. It was so easy to install everything lined up perfectly. Plugged the adapter in and the light worked. No running wires through the frame, no extra wires to connect to battery, and no splicing. The lighting was more than enough low and high beam.
