title: Can police car colored flash light induce electroencephalographic discharges and seizures?
abstract: OBJECTIVE
  To explore the epileptogenic potential of a newly introduced police car flash light device (930 Heliobe Lightbar).
  
  
  METHODS
  A 930 Heliobe Lightbar was installed in the EEG laboratory. Thirty patients with known epilepsy, 30 subjects with chronic headache who were otherwise healthy and 15 healthy volunteers were examined.
  
  
  RESULTS
  All the subjects signed an informed consent and underwent an EEG during which photostimulation was performed with the standard stroboscope and later with the Police lightbar. In all 75 examined the lightbar did not induce clinical or electrographic seizures. In a single patient with epilepsy the lightbar enhanced epileptiform activity induced by standard photic stimulation.
  
  
  CONCLUSIONS
  In this study the new Police lightbar was found to be non-epileptogenic.
