Halogen rotating beacons have high warning effectiveness from the use of parabolic reflectors and high-quality bulbs.
Halogen bulbs are more efficient and longer lasting than standard incandescent bulbs.
These beacons can be more economical to purchase but the use of movable parts causes mechanical wear, so the expected service life can be expected to be lower than Xenon or LED beacons.
Halogen beacons are good where the beacon is used infrequently and longevity compared to LED beacons is not so important.
