"The system isn't vehicle specific, so it relieves the necessity of having to offer a couple hundred SKUs, which was a pain for us, as well as for our distributors to stock and the customers. It's now one-size- fits all, regardless of year, make or model," Robinson says. Meanwhile, a growing trend in the auto- motive industry is to change the electronics such that you can no longer wire the lighting for dinghy towing. "Car manufacturers are either adding features for consumers, light-weighting the vehicles, or taking money out of the car, which includes taking a lot of the wire out of the vehicles – it's heavy and expensive," Robinson explains. Historically, auto manufacturers provided one wire for the brake lights and another for the taillights. Automobile manufacturers have now developed a system using one wire that carries both the brake light and the taillight signal. They do this by varying the voltage. (A brake light requires 12 volts, while a taillight carries 9 volts.) "The problem arises when a motorhome is connected to the car, because the RV just has 12 volts, so when those volts hit the tail- lights, it looks like the brake lights are on." Roadmaster's new product, Smart Diode, is "smart" enough to recognize the variable voltage in the towed car and will automat- ically carry the appropriate voltage to the dinghy's lights. (The smart diodes are nec- essary on any new vehicle that uses variable voltage lighting.) Also of note for all Roadmaster products, Robinson says the company has upgraded Company founder and owner Jerry Edwards examines towing components on the manufacturing floor.
