Researchers evaluated the safety and effectiveness of equipping MnDOT snowplows with LED-based strobe lights, which are more efficient and cost-effective than standard HID lights. Results showed that while LED lights are as conspicuous as HID for standard driving conditions and viewing angles, they are not as visible when approached from a variety of other viewing angles. Further research is needed to determine whether these angles are relevant to safety.
