The amount of time it takes to install mirror mount strobe lights vary depending on the type and model you purchase. Generally, installation is relatively easy as these types of lights typically come with a mounting bracket and wiring harness so that they can be securely attached to your vehicle’s mirrors. Depending on how familiar you are with electrical wiring, the entire installation process could take anywhere from 30 minutes to an hour or more if additional components such as switches or relay boards are needed.
