Install Low-Voltage Landscape Lighting Along a Driveway

Low-voltage landscape lighting transforms a driveway from a purely functional concrete strip into a welcoming nighttime feature. A few well-placed lights along the edge define the space, improve safety by marking the pavement edge, and add genuine character without breaking your electrical code or your back. This isn't a job that requires a licensed electrician—low-voltage systems (typically 12 volts) are safe to install yourself, forgiving of mistakes, and modular enough that you can add lights later if you want. The real work is the planning: deciding where lights should live, running the cable neatly, and making sure your transformer is positioned where it won't get buried or kicked.

  1. Map Your Light Zones. Walk the driveway at night and imagine where pools of light would feel natural—typically 3 to 4 feet apart along one or both edges, slightly forward of the driveway line. Measure the total distance from your planned transformer location (near an outdoor outlet) to the farthest light. Account for cable that runs along the driveway edge plus any routing around obstacles. Add 10 percent to your measurement for slack and connections. This number determines your cable gauge and transformer wattage.
  2. Install the Power Hub. Select a transformer rated for your total fixture wattage (most residential kits run 60–300 watts). Mount it on an exterior wall within 6 feet of a GFCI-protected outlet, under an eave or in a weatherproof enclosure. The transformer should be above ground level and away from foot traffic. Plug it in and verify it powers on before running any cable.
  3. Route Your Cable. For a permanent installation, dig a shallow trench (2–3 inches deep) along the driveway edge using a flat spade or edging tool. Alternatively, lay the cable on the surface and stake it down with landscape staples every 12 inches—this works fine and is easier to modify later. Run the cable in a continuous line from the transformer output, staying off the driveway surface itself to avoid damage.
  4. Space and Stake Lights. Starting at the transformer, place the first fixture 3–4 feet down the line, then space the rest at 3–4 foot intervals. Most low-voltage lights have a stake or post that pushes into soil or mulch. Position each fixture so its light beam points toward the driveway or outward at a low angle—not up into trees or sky. Press the stake firmly into the ground so the light sits level and won't tip in wind.
  5. Wire Each Fixture. Most low-voltage systems use simple push-connect terminals or small terminal screws on the back of each light. Strip about 0.5 inches of insulation from the cable end, insert the two wires into the fixture connectors (polarity doesn't usually matter on LED systems), and secure them. Work methodically from the transformer outward. Don't daisy-chain connectors or splice cable with tape—always use the fixture's built-in terminals.
  6. Verify and Adjust. Once all connections are made, power on the transformer and check that every light illuminates. Walk the driveway and note any fixtures that seem too dim, too bright, or aimed wrong. Rotate or tilt individual lights to adjust their beam direction. If a light doesn't turn on, unplug the transformer, reseat its connector, and try again.
  7. Lock Down Your Cable. Once all lights are working, secure any exposed cable with landscape staples every 12–18 inches, or bury it fully in the trench and backfill with mulch. Keep cable away from the driveway surface where car tires or snow removal equipment could damage it. If burying, mark the cable route mentally or with a small map so future you knows where it runs.
  8. Document and Finish. Rake mulch smooth, remove any debris from the work area, and dispose of packaging. Check the transformer one more time to confirm it's plugged in and any timer settings are correct. Note the locations of all lights on a simple sketch in case you need to dig near them in the future.
