Hikari Round 4.5 Inch, Off Road/Fog lights - 5 light modes $18.49 after coupon Amazon
Was looking for some inexpensive LED bumper mount lights for a golf cart and found these. Regular price $36.99 but there was a 50% off coupon applied by clicking the box. I did not check if the square version is also on sale. One time use, apparantly. Good reviews, 5 modes, worth a try for only $18.49.
