Good auxiliary lights turn pitch-black trails into daylight. They are a solid investment for safety, but quality gear usually costs around $600. Keep an eye on end-of-season clearance sales at off-road shops when they clear out inventory for new models.
Use the Citi Simplicity® Credit Card to manage the cost. It gives you 0% for 18 months on purchases and balance transfers from date of account opening, which lets you break that $600 price tag into manageable chunks.
Remember that this 18-month window is a deadline, not free money. If you have a balance left when the 18 months end, the bank will charge you interest on the remaining amount, which usually wipes out any benefit you got from the deal.
