VizbriteLight Up Dog Harness No Pull LED Dog Harness with Handle Rechargeable Lighted Dog Vest Harness for Small/Medium/Large/X-Large Size Dogs No Pull, 4 Point Adjustable Dog Harness

Fits my dog perfect with adjustable straps, I can see exactly where she is at night time play at park , my dog looks so cute with it on!

The XL fits my Australian Shepherd perfectly. He is 80lbs, chest is 38", and his neck is 18" if that help for sizing up what you're looking for. The vest is easy to adjust, put on and take of Mr. Laramous. One press of the button the light is a bright steady green, second press the light flashes, one more press and it is off. I actually ordered a large thinking it would fit and I didn't bother to measure before ordering. When I put it on Mr. Laramous though it was just a little to tight. Since the size issue was on me I asked if I could just exchange the L for an XL. The seller responded immediately letting me know that I can keep the L and order the XL and they'll refund the cost of one. All I had to do was provide measurements so they could confirm their size chart and I had to let them know if the XL fit or not when I got it. The whole process was fast, excellent communication & product!

This is a great harness for finding my dog in the dark. I have 4 acres and it's hard to know where he is when it's dark outside. This definitely solved the problem. I now call him my giant firefly because the harness is the same color as the fireflies. The only downside to this harness is that it's easy to escape from if you have a dog smart enough to figure out how.

I bought these because I have two black labs who are difficult to see in the dark. We went on a trip and on our first pee break, our 1 yr old lab got scared and was easily able to back out of the harness because it had loosened on its own between when we got in the car and when we stopped. He ran and was hit by a car. We are MORTIFIED and in terrible grief. I am returning these ASAP when we are home.

Loved the harness, it was bright and looked like it would be comfortable for my dog. However, it was unwearable because the sizing was way off from the size chart provided. For reference I purchased the small based on the chart. My dog's neck is 17.5' and chest is 21" and even on the absolute tightest setting you can get the harness to she could step out of it. Make sure you size down if you try this out.
