Try not to use a headlight when running the lake. That really makes it hard for other boaters to see which direction you're going. Those bright spotlights and trolling motor lights are horrible! I've fished night tournaments against guys that use those and it makes me so mad because I can hardly see what direction I need to go. Please don't use those when navigating a lake. I also only try to use a light when I'm making a super-tight pitch or cast. Otherwise I just use my eyes. It takes a little time to get used to it but in the end it'll work out.
As far as techniques go, anything you use during the day will work at night. I recommend you plan your trips an hour after sunset. Bass' eyes need time to adjust to night vision and you won't get many bites at all the first hour after sunset. Trust me, I night fish 90% of the time during the Summer.
Docks lights are simple and easy to fish. Approach them and stay about 50 feet away and cast in to them. A small fluke on a dropshot or a 3-5 inch swimbait on a jighead has produced a lot of my catches.
If your lake doesn't have any dock lights then go find shallow cover that's next to deep water. Bass come up shallow to feed at night and that's where they'll be.
Some of my favorite baits for shallow cover at night are:Strike King Tour Grade Night Spinnerbait
This is my go-to spinnerbait for nighttime. You can really feel the thump of the blade and this bait will stand up to the biggest fish out there. Super high quality and it's been money for me. Fin Junkie Flipping Jig
Another bait that has been killer for me is this flipping jig. This is a premium jig with a high quality skirt and a sharp, beefy hook. This is my favorite jig! Gambler Mega Daddy
This is a good beefy craw for nighttime. The flappers move a lot of water and it has an awesome swimming action, which is great for nighttime fishing! They're durable, have garlic scent, and they're inexpensive. D&M Flippin' Craw
If you want more of a realistic looking craw and one that doesn't have a ton of action, then the D&M Flippin' Craw is for you. This is my favorite craw bait. These baits are custom made and are super reliable. It's a perfect craw bait for nighttime fishing because it's realistic and it offers a bulky profile. Zoom Brush Hog
Another favorite bait of mine for nighttime fishing is the Brush Hog. It's been around for years and it's a proven winner. Can't go wrong with these at night!
Night fishing can be tricky but if you keep going, it'll pay off big time sooner or later.
