hi yes makes a difference much brighter less drain on battery used 36 led from ebay have not fitted the indicator main lamp din't want to butcher the wiring by fitting load resistors in parallel but fitted to side repeaters ,interior,fog brake and side lights been in for three years had some fail due to manufacturing flaws soon remedied by solder ,will fit indicator's when I get hold of a electronic flasher unit so no load resistors that require fitting
