Quick answer: The GTW LED Turn Signal & Horn Kit is the best all-around pick for most EZGO, Club Car, and Yamaha owners going street-legal — a self-canceling LED signal kit with a built-in horn and brake-light interconnect, priced around $79.99. Budget shoppers get a functional signal-only setup from the 10L0L Turn Signal Switch Kit (about $54.99). Owners who want the most complete street-legal package, including a horn and hazard function in one wiring harness, should step up to the Madjax Deluxe Signal & Horn Kit (roughly $99.99). Most state LSV laws require self-canceling signals per the National Golf Cart Association’s street-legal checklist, so confirm that feature before buying any kit.

1. GTW LED Turn Signal & Horn Kit — Best Overall
GTW LED Turn Signal & Horn Kit
- Self-canceling LED signal switch pod with a built-in horn button, wired to interconnect with the cart's existing tail light housing for brake-light activation, per GTW's install guide.
- Fits EZGO TXT/RXV, Club Car DS/Precedent, and Yamaha Drive/Drive2 with the factory wiring channel, so no custom drilling is typically needed.
- LED bulbs draw a fraction of the current incandescent kits use, which matters most on 48V carts running the signal circuit off the DC-DC converter rather than the main battery pack.
Keep your cart rolling — get batteries, covers, and accessories in two days with a free 30-day Amazon Prime trial, useful if a wiring connector or fuse turns out to be missing from the box and a local shop can’t get you one same-day. The GTW kit is the default pick here because it bundles a horn and self-canceling signals in a single harness at a mid-range price.
2. 10L0L Turn Signal Switch Kit — Best Budget
10L0L Turn Signal Switch Kit
- Manual-cancel turn signal switch with LED indicator lights, sized for the same EZGO/Club Car/Yamaha fitments as the pricier kits.
- No horn included, so owners who already have a working horn and just need signals to pass an LSV inspection get the lowest price of the three.
- Manual cancel means flipping the switch back after each turn — a real difference from self-canceling kits that some state DMVs specifically check for at LSV registration.
3. Madjax Deluxe Signal & Horn Kit — Best Complete Street-Legal Kit
Madjax Deluxe Signal & Horn Kit
- Self-canceling signals, integrated horn, and a hazard-flash function in one wiring harness — the most complete LSV-equipment coverage of the three kits here.
- Includes a pre-wired brake-light interconnect harness, which shortens the install for carts that don't already have brake lights hooked into the tail light housing.
- Backed by a 1-year warranty, the longest coverage of the three, which matters on a part that sits exposed to weather at the dash.
How to choose a golf cart turn signal kit
- Confirm self-canceling if you’re going street-legal. Per the National Golf Cart Association’s street-legal equipment checklist, most state LSV laws expect self-canceling signals rather than manual-reset switches — check your state DMV’s exact list before buying the budget manual-cancel option.
- Check whether a horn is already installed. If your cart doesn’t have one, a combo kit like the GTW or Madjax saves a second purchase and a second wiring job compared to buying signals and a horn separately.
- Verify your cart already has working tail/brake lights. Turn signal kits typically interconnect with the existing tail light housing for brake activation — carts without factory brake lights need that wired first, which adds time beyond the signal kit install itself.
- Match the kit to your cart brand’s wiring channel. EZGO, Club Car, and Yamaha route dash wiring differently enough that a kit sized for one brand’s factory channel may need extra drilling on another.
The bottom line
The GTW LED Turn Signal & Horn Kit is the right first buy for most owners prepping a cart for street-legal LSV registration — self-canceling signals and a horn in one harness at a fair price. The 10L0L kit is the better call if your cart already has a working horn and you just need signals to check a box on inspection. Owners who want the most complete equipment coverage in a single install, including a hazard function, should go with the Madjax Deluxe Kit. Whichever kit you pick, confirm your state’s exact LSV equipment requirements first — see our street-legal golf cart guide for the full checklist, and our best golf cart accessories roundup for what most owners add next.
Last updated: August 25, 2026. Prices rechecked against current retailer listings — third-party sellers show GTW- and Madjax-branded turn signal kits under several different bundle tiers (some including a full light kit, column cover, or hazard control box beyond the signal-and-horn kits described here), so the exact SKUs referenced above couldn’t be independently reconfirmed against a single consistent listing this pass. The existing prices are kept as-is until a direct-from-manufacturer match is found.
