To use when

The original turn signals were 21 W

If they were 10 W, you need code DNLWHS12700 instead.

Equipment

Package contents

Pair of load resistors

One resistive load for each arrow replaced

Installation

Assembly note

The resistors heat up depending on the function

They must be mounted on a heat-dissipating metal surface, away from plastics and wiring.

Description Original 21 W LED turn signal anti-hyperflash resistors DNLWHS12800

Code DNLWHS12800 — DENALI code DNL.WHS.12800

Pair of load resistors to install when replacing incandescent turn signals with LED indicators. Without them, the turn signals flash at twice the normal rate: the LED draws a fraction of the current used by the bulb, and the motorcycle’s control unit interprets this drop as a burned-out bulb.

These are the version for motorcycles whose original turn signals were rated at 21 W. If they were rated at 10 W, use code DNLWHS12700.

One resistor is required for each replaced turn signal: one package covers a pair, either front or rear.

Why choose it

Non è un accessorio, è un pezzo necessario. Un LED assorbe una frazione di quello che assorbiva la lampadina che sostituisce, e la centralina della moto legge quel calo come freccia bruciata: la conseguenza è il lampeggio a frequenza doppia. Le resistenze riportano l'assorbimento al valore atteso e tutto torna normale.

Sono la versione per le moto le cui frecce originali erano da 21 W. Se erano da 10 W serve il codice DNLWHS12700.

Documents and manufacturer

Le resistenze di carico dissipano in calore l'energia che la lampadina originale avrebbe consumato: durante il funzionamento scaldano. Vanno fissate su una superficie metallica che dissipi, lontano da plastiche, cablaggi e serbatoio.

DENALI riconosce 5 anni di garanzia convenzionale del produttore, che si aggiunge ai 24 mesi di garanzia legale di conformità.

How does it work, in detail?

  • They bring the intake to the value the motorcycle’s control unit expects.
When the LED turn signals flash too quickly

When the LED turn signals flash too quickly

An LED turn signal draws much less power than a bulb turn signal. The motorcycle's flasher relay interprets this drop as a burned-out bulb and speeds up the flashing. The resistor restores the load expected by the electrical system, and the rhythm returns to normal.

This version is for motorcycles with original 21 W turn signals. If yours are 10 W, the correct version is code DNLWHS12700.

FAQs

For more information, see our FAQ of frequently asked questions.

How can I tell whether my turn signals were 10 W or 21 W?

The wattage is printed on the bulb you remove: you’ll find it on the bulb itself or the base. If the bulb has already burned out or is illegible, the value is listed in the motorcycle’s owner’s manual, in the bulb table. If you’re unsure, tell us the motorcycle model and year.

Do I need two or four?

One replacement shock absorber for each spring. If you replace only the two front ones or only the two rear ones, one package is enough; if you replace all four, you need two.

Can I avoid them by using a CANsmart control unit?

In many cases, yes: if the turn signals are controlled by the control unit instead of the motorcycle’s original circuit, the hyperflashing problem does not occur. However, it depends on the model and how you connect them: if you don’t have a CANsmart, resistors are required.
