Lights are all very similar and I try not to spend too much. I dislike USB re-chargeable, haven’t gotten long term reliability out of the 2 I tried, now I buy what’s on sale at REI or my LBS. Are you just looking for blinkers ? Or night riding ?.

Drivers are worse. There’s a real problem with texting and driver inattention, with cyclists getting run down on the shoulder for no obvious reasons. OTOH, I ride choose quite roads when possible, as well as times that see reduced traffic, so try to alleviate the danger. Don’t judge current conditions though, CV crisis as seen a drastic reduction in traffic volume, almost like every day, afternoons even, are like 7AM on Sunday. It will pass in a few months though.
