Dodge - Ram (Dual Headlight)

VEHICLE: Dodge Ram

ISSUE: Daytime running lights cause flickering if low beams are not switched on.

SUMMARY: This issue affects DUAL version of the Dodge Ram only. Those with the QUAD lighting system are not affected. Normally we can work around Daytime Running Light issues by tapping a capacitor to the DRL rail. This causes the DRL to turn on full power instead of flickering. In this case, the DRL uses the high beam, and if the DRL runs at full power, this is akin to running with high beams on all the time (when the lows are not switched on). Unfortunately no "canceller" can resolve this issue nor are there any commercially available "harnesses" to deal with this situation. There are, however, some smaller or custom shops which build their own DIY harnesses.

RESOLUTION: There are only several solutions:

  1. Disable the Daytime Running Light system (recommended option).
  2. Always run with the low beams switched on.
  3. Run a bi-halogen application *

Using a bi-halogen application effectively deals with the DRL issue as the high beam is a small halogen bulb. Unfortunately this also means the high beam function is useless as it is an underpowered bulb. An alternate option is to run a single-xenon bulb (low beam only) but in that case, a capacitor must be tapped in to deal with flickering.
