I installed a set of PL-940 Pilot Remote Series high performance driving lights. It claims that the remotes work up to 50 feet or yards or something, yet it barely works 5 feet from the reciever. Is there a way to boost the signal? With some recievers they can only use a short antenna, I'm not sure if mine is one of those. The antenna is about 6 inches long, and is at the highest part in my engine compartment, like instructed.
