For a model railroad track & layout, the first choice is not simply which accessory costs less: do you need to feed power into HO rails, or add illuminated detail to an N scale scene? These two choices solve different problems. The 1:87 HO connector is an electrical accessory for a DIY setup, while the 1:160 signal set adds three wired LED signals. Pick by scale and job first, then use the price gap as a tie-breaker.
Quick verdict
Choose the 1:87 HO Scale Model Railway Train Track Electric Wire Rail Power Connector DIY if you need a rail power connection for an HO layout and want the lower listed price. Choose the 3pcs Model Railway N Scale 1:160 Signals 3-LEDs Green Yellow Red Track Lights if your layout is N scale and the goal is illuminated signaling detail. They are not interchangeable: one is a power connector, while the other is a three-signal lighting set.

Where each product wins
1:87 HO Scale Electric Wire Rail Power Connector
It wins when the layout is HO and the missing piece is a rail power connection. The title identifies that function directly, while the description specifies black plastic construction and a 12-18V DC supply. It also has the lower listed price in the comparison. That combination makes it the straightforward choice for a DIY electrical task, provided the project is HO rather than N.
3pcs N Scale 1:160 Signal Lights

It wins when the layout is N scale and visual signaling matters more than feeding power to the rails. The set brings three signals and three LED colors, with wires included and a pre-wired resistor described for 9-18V operation. Its 12V AC or DC specification further defines it as a lighting accessory rather than a rail connector. Choose it for ready-to-go signal detail, not as a substitute for the HO electrical accessory.
Product notes
1:87 HO Scale Track Electric Wire Rail Power Connector

Choose the 1:87 HO Scale Model Railway Train Track Electric Wire Rail Power Connector DIY when the layout is HO scale and the job is adding a rail power connection rather than scenery. Its description identifies a black plastic connector for a DC supply in the 12-18V range, while the DIY wording suits a hands-on project. The package is one piece, keeping the purchase focused on a single connection point. The limitation is equally specific: it is not a set of track sections or signals, and the package does not extend beyond that connector. Its role is therefore narrow but clear-an HO electrical accessory for a 12-18V DC setup, not a scenic lighting set.
3pcs N Scale 1:160 Signal Lights
The 3pcs Model Railway N Scale 1:160 Signals 3-LEDs Green Yellow Red Track Lights fits a shopper whose main goal is visible signaling detail on an N scale layout. It includes three signals with green, yellow, and red LEDs, plus wires and pre-wired resistors; the assembly status is ready to go/pre-built. The signals are specified for 12V AC or DC, with 20mA operating current for each LED, and the resistor is described for 9-18V operation. The limitation is its job: it adds illuminated signals, not an HO rail power connector or a length of track. Its higher listed price also matters if the project does not need lighting detail.
Final choice by use case
- HO electrical connection: Select the 1:87 HO Scale Model Railway Train Track Electric Wire Rail Power Connector DIY for its HO scale and clearly stated rail power connector role.
- N scale scenic detail: Select the 3pcs Model Railway N Scale 1:160 Signals 3-LEDs Green Yellow Red Track Lights for three signals, three LED colors, and a pre-built format.
- Price-first tie-breaker: The listed price gap is USD 7.00, from USD 11.99 to USD 18.99. The lower price belongs to the connector, but it should influence the decision only when an HO electrical connection is what the layout needs.
