 
 Hi River. Most 2015 sedans use Schrader valves, which are short metal stems with a spring pin in the center. A compatible gauge will state Schrader or show a car tire chuck; avoid Presta only bike gauges or anything needing an adapter. On arrival, test fit cold by removing the cap and pressing the gauge squarely onto the valve; a brief hiss then a steady reading means a good seal, continuous hissing means poor fit or a damaged head. For low light and accuracy, choose a digital unit with a backlit display and lighted nozzle, at least 0.5 PSI resolution, and a range to 100 PSI; these are common under your budget. Verify accuracy by comparing with a second gauge; within 1 to 2 PSI is acceptable. If the dash light stays on, set pressure to the door placard value when cold and check the valve with soapy water; bubbles indicate a loose or leaking core.
Adding one thing - If you want something under $15 that’s easy to read the basic digital AstroAI or Tekton gauges are solid and typically have a backlit display and lighted tip for low light. Check pressures first thing in the morning when the tires are cold; they change about 1 psi for every 10°F swing. If your old gauge wouldn’t seal, it was likely a bike/Presta type or the rubber gasket was dried out - press straight and firmly for a quick, clean reading. After setting to the door placard, the TPMS light usually clears after a short drive; if not, you may have a slow leak or a slightly loose valve core.
