So my 16 year old son and I just bought our first kayaks this past weekend. We are hauling them in the back of our pickup truck and they extend well beyond the bed. We are looking at bed extenders, but also concerned about lighting if traveling after dark. We are using a flag during the daytime but do not want to restrict our travels to daytime only. Any ideas on easily rigging a light on that extended load? I have looked for different "temporary" lighting but only finding magnetic lights right now. Thanks in advance for any help.
