I am intending to write this guide to avoid a few pitfalls when purchasing vehcle waning equipment. Whatever you do dont buy anything from China etc. These units may look exaxtly like for example a Whelen Dual Talon. However they are poor quality, burn out within 4-5 hours use, are nowhere near as bright and are ultimately not safe. There are loads of dash lights, lightbars and beacon which are exact copies of the real deal made by Whelen, Premier Hazard/Code3 and Vision Alert to name a few.
What you get is what you pay for ultimately!!!!
If the light is made by Whelen/Woodway, Premier Hazard/Code 3, Vision Alert, Dorman, Lucas/LAP, Britax or Federal Signal then it will be good quality and function as it should. It will cost a lot more, however it is worth it!!
Overall buy the best!! Dont buy crap because
